Convert all enumerations to use `enum class`. Specifically, take the old code that looks like this: class Foo { enum { X = 1, Y = 2 }; int kind; } ... foo.kind = Foo::X; ... and convert it to this: class Foo { enum class Kind : uint32_t { X = 1, Y = 2 }; Kind kind; } ... foo.kind = Foo::Kind::X; (In some cases the enumeration would not be in the class namespace, such as when it is generally useful.) The benefits are as follows: * The type of the field gives a clear indication of intent, both to humans and tools (such as binding generators). * The compiler is able to automatically warn when a switch is not exhaustive; but this is currently suppressed by the default: ssassert(false, ...) idiom. * Integers and plain enums are weakly type checked: they implicitly convert into each other. This can hide bugs where type conversion is performed but not intended. Enum classes are strongly type checked. * Plain enums pollute parent namespaces; enum classes do not. Almost every defined enum we have already has a kind of ad-hoc namespacing via `NAMESPACE_`, which is now explicit. * Plain enums do not have a well-defined ABI size, which is important for bindings. Enum classes can have it, if specified. We specify the base type for all enums as uint32_t, which is a safe choice and allows us to not change the numeric values of any variants. This commit introduces absolutely no functional change to the code, just renaming and change of types. It handles almost all cases, except GraphicsWindow::pending.operation, which needs minor functional change.

Enable exhaustive switch coverage warnings as an error, and use them. Specifically, this enables -Wswitch=error on GCC/Clang and its MSVC equivalent; the exact way it is handled varies slightly, but what they all have in common is that in a switch statement over an enumeration, any enumerand that is not explicitly (via case:) or implicitly (via default:) handled in the switch triggers an error. Moreover, we also change the switch statements in three ways: * Switch statements that ought to be extended every time a new enumerand is added (e.g. Entity::DrawOrGetDistance(), are changed to explicitly list every single enumerand, and not have a default: branch. Note that the assertions are kept because it is legal for a enumeration to have a value unlike any of its defined enumerands, and we can e.g. read garbage from a file, or an uninitialized variable. This requires some rearranging if a default: branch is undesired. * Switch statements that ought to only ever see a few select enumerands, are changed to always assert in the default: branch. * Switch statements that do something meaningful for a few enumerands, and ignore everything else, are changed to do nothing in a default: branch, under the assumption that changing them every time an enumerand is added or removed would just result in noise and catch no bugs. This commit also removes the {Request,Entity,Constraint}::UNKNOWN and Entity::DATUM_POINT enumerands, as those were just fancy names for zeroes. They mess up switch exhaustiveness checks and most of the time were not the best way to implement what they did anyway.

Convert all enumerations to use `enum class`. Specifically, take the old code that looks like this: class Foo { enum { X = 1, Y = 2 }; int kind; } ... foo.kind = Foo::X; ... and convert it to this: class Foo { enum class Kind : uint32_t { X = 1, Y = 2 }; Kind kind; } ... foo.kind = Foo::Kind::X; (In some cases the enumeration would not be in the class namespace, such as when it is generally useful.) The benefits are as follows: * The type of the field gives a clear indication of intent, both to humans and tools (such as binding generators). * The compiler is able to automatically warn when a switch is not exhaustive; but this is currently suppressed by the default: ssassert(false, ...) idiom. * Integers and plain enums are weakly type checked: they implicitly convert into each other. This can hide bugs where type conversion is performed but not intended. Enum classes are strongly type checked. * Plain enums pollute parent namespaces; enum classes do not. Almost every defined enum we have already has a kind of ad-hoc namespacing via `NAMESPACE_`, which is now explicit. * Plain enums do not have a well-defined ABI size, which is important for bindings. Enum classes can have it, if specified. We specify the base type for all enums as uint32_t, which is a safe choice and allows us to not change the numeric values of any variants. This commit introduces absolutely no functional change to the code, just renaming and change of types. It handles almost all cases, except GraphicsWindow::pending.operation, which needs minor functional change.

Enable exhaustive switch coverage warnings as an error, and use them. Specifically, this enables -Wswitch=error on GCC/Clang and its MSVC equivalent; the exact way it is handled varies slightly, but what they all have in common is that in a switch statement over an enumeration, any enumerand that is not explicitly (via case:) or implicitly (via default:) handled in the switch triggers an error. Moreover, we also change the switch statements in three ways: * Switch statements that ought to be extended every time a new enumerand is added (e.g. Entity::DrawOrGetDistance(), are changed to explicitly list every single enumerand, and not have a default: branch. Note that the assertions are kept because it is legal for a enumeration to have a value unlike any of its defined enumerands, and we can e.g. read garbage from a file, or an uninitialized variable. This requires some rearranging if a default: branch is undesired. * Switch statements that ought to only ever see a few select enumerands, are changed to always assert in the default: branch. * Switch statements that do something meaningful for a few enumerands, and ignore everything else, are changed to do nothing in a default: branch, under the assumption that changing them every time an enumerand is added or removed would just result in noise and catch no bugs. This commit also removes the {Request,Entity,Constraint}::UNKNOWN and Entity::DATUM_POINT enumerands, as those were just fancy names for zeroes. They mess up switch exhaustiveness checks and most of the time were not the best way to implement what they did anyway.

The benefits are as follows: * The type of the field gives a clear indication of intent, both to humans and tools (such as binding generators). * The compiler is able to automatically warn when a switch is not exhaustive; but this is currently suppressed by the default: ssassert(false, ...) idiom. * Integers and plain enums are weakly type checked: they implicitly convert into each other. This can hide bugs where type conversion is performed but not intended. Enum classes are strongly type checked. * Plain enums pollute parent namespaces; enum classes do not. Almost every defined enum we have already has a kind of ad-hoc namespacing via `NAMESPACE_`, which is now explicit. * Plain enums do not have a well-defined ABI size, which is important for bindings. Enum classes can have it, if specified. We specify the base type for all enums as uint32_t, which is a safe choice and allows us to not change the numeric values of any variants. This commit introduces absolutely no functional change to the code, just renaming and change of types.

Enable exhaustive switch coverage warnings as an error, and use them. Specifically, this enables -Wswitch=error on GCC/Clang and its MSVC equivalent; the exact way it is handled varies slightly, but what they all have in common is that in a switch statement over an enumeration, any enumerand that is not explicitly (via case:) or implicitly (via default:) handled in the switch triggers an error. Moreover, we also change the switch statements in three ways: * Switch statements that ought to be extended every time a new enumerand is added (e.g. Entity::DrawOrGetDistance(), are changed to explicitly list every single enumerand, and not have a default: branch. Note that the assertions are kept because it is legal for a enumeration to have a value unlike any of its defined enumerands, and we can e.g. read garbage from a file, or an uninitialized variable. This requires some rearranging if a default: branch is undesired. * Switch statements that ought to only ever see a few select enumerands, are changed to always assert in the default: branch. * Switch statements that do something meaningful for a few enumerands, and ignore everything else, are changed to do nothing in a default: branch, under the assumption that changing them every time an enumerand is added or removed would just result in noise and catch no bugs. This commit also removes the {Request,Entity,Constraint}::UNKNOWN and Entity::DATUM_POINT enumerands, as those were just fancy names for zeroes. They mess up switch exhaustiveness checks and most of the time were not the best way to implement what they did anyway.

Replaced RGB-color integers with dedicated data structure RGB colors were represented using a uint32_t with the red, green and blue values stuffed into the lower three octets (i.e. 0x00BBGGRR), like Microsoft's COLORREF. This approach did not lend itself to type safety, however, so this change replaces it with an RgbColor class that provides the same infomation plus a handful of useful methods to work with it. (Note that sizeof(RgbColor) == sizeof(uint32_t), so this change should not lead to memory bloat.) Some of the new methods/fields replace what were previously macro calls; e.g. RED(c) is now c.red, REDf(c) is now c.redF(). The .Equals() method is now used instead of == to compare colors. RGB colors still need to be represented as packed integers in file I/O and preferences, so the methods .FromPackedInt() and .ToPackedInt() are provided. Also implemented are Cnf{Freeze,Thaw}Color(), type-safe wrappers around Cnf{Freeze,Thaw}Int() that facilitate I/O with preferences. (Cnf{Freeze,Thaw}Color() are defined outside of the system-dependent code to minimize the footprint of the latter; because the same can be done with Cnf{Freeze,Thaw}Bool(), those are also moved out of the system code with this commit.) Color integers were being OR'ed with 0x80000000 in some places for two distinct purposes: One, to indicate use of a default color in glxFillMesh(); this has been replaced by use of the .UseDefault() method. Two, to indicate to TextWindow::Printf() that the format argument of a "%Bp"/"%Fp" specifier is an RGB color rather than a color "code" from TextWindow::bgColors[] or TextWindow::fgColors[] (as the specifier can accept either); instead, we define a new flag "z" (as in "%Bz" or "%Fz") to indicate an RGBcolor pointer, leaving "%Bp"/"%Fp" to indicate a color code exclusively. (This also allows TextWindow::meta[][].bg to be a char instead of an int, partly compensating for the new .bgRgb field added immediately after.) In array declarations, RGB colors could previously be specified as 0 (often in a terminating element). As that no longer works, we define NULL_COLOR, which serves much the same purpose for RgbColor variables as NULL serves for pointers.

Convert all enumerations to use `enum class`. Specifically, take the old code that looks like this: class Foo { enum { X = 1, Y = 2 }; int kind; } ... foo.kind = Foo::X; ... and convert it to this: class Foo { enum class Kind : uint32_t { X = 1, Y = 2 }; Kind kind; } ... foo.kind = Foo::Kind::X; (In some cases the enumeration would not be in the class namespace, such as when it is generally useful.) The benefits are as follows: * The type of the field gives a clear indication of intent, both to humans and tools (such as binding generators). * The compiler is able to automatically warn when a switch is not exhaustive; but this is currently suppressed by the default: ssassert(false, ...) idiom. * Integers and plain enums are weakly type checked: they implicitly convert into each other. This can hide bugs where type conversion is performed but not intended. Enum classes are strongly type checked. * Plain enums pollute parent namespaces; enum classes do not. Almost every defined enum we have already has a kind of ad-hoc namespacing via `NAMESPACE_`, which is now explicit. * Plain enums do not have a well-defined ABI size, which is important for bindings. Enum classes can have it, if specified. We specify the base type for all enums as uint32_t, which is a safe choice and allows us to not change the numeric values of any variants. This commit introduces absolutely no functional change to the code, just renaming and change of types. It handles almost all cases, except GraphicsWindow::pending.operation, which needs minor functional change.

Replaced RGB-color integers with dedicated data structure RGB colors were represented using a uint32_t with the red, green and blue values stuffed into the lower three octets (i.e. 0x00BBGGRR), like Microsoft's COLORREF. This approach did not lend itself to type safety, however, so this change replaces it with an RgbColor class that provides the same infomation plus a handful of useful methods to work with it. (Note that sizeof(RgbColor) == sizeof(uint32_t), so this change should not lead to memory bloat.) Some of the new methods/fields replace what were previously macro calls; e.g. RED(c) is now c.red, REDf(c) is now c.redF(). The .Equals() method is now used instead of == to compare colors. RGB colors still need to be represented as packed integers in file I/O and preferences, so the methods .FromPackedInt() and .ToPackedInt() are provided. Also implemented are Cnf{Freeze,Thaw}Color(), type-safe wrappers around Cnf{Freeze,Thaw}Int() that facilitate I/O with preferences. (Cnf{Freeze,Thaw}Color() are defined outside of the system-dependent code to minimize the footprint of the latter; because the same can be done with Cnf{Freeze,Thaw}Bool(), those are also moved out of the system code with this commit.) Color integers were being OR'ed with 0x80000000 in some places for two distinct purposes: One, to indicate use of a default color in glxFillMesh(); this has been replaced by use of the .UseDefault() method. Two, to indicate to TextWindow::Printf() that the format argument of a "%Bp"/"%Fp" specifier is an RGB color rather than a color "code" from TextWindow::bgColors[] or TextWindow::fgColors[] (as the specifier can accept either); instead, we define a new flag "z" (as in "%Bz" or "%Fz") to indicate an RGBcolor pointer, leaving "%Bp"/"%Fp" to indicate a color code exclusively. (This also allows TextWindow::meta[][].bg to be a char instead of an int, partly compensating for the new .bgRgb field added immediately after.) In array declarations, RGB colors could previously be specified as 0 (often in a terminating element). As that no longer works, we define NULL_COLOR, which serves much the same purpose for RgbColor variables as NULL serves for pointers.

Some of the new methods/fields replace what were previously macro calls; e.g. RED(c) is now c.red, REDf(c) is now c.redF(). The .Equals() method is now used instead of == to compare colors. RGB colors still need to be represented as packed integers in file I/O and preferences, so the methods .FromPackedInt() and .ToPackedInt() are provided. Also implemented are Cnf{Freeze,Thaw}Color(), type-safe wrappers around Cnf{Freeze,Thaw}Int() that facilitate I/O with preferences. (Cnf{Freeze,Thaw}Color() are defined outside of the system-dependent code to minimize the footprint of the latter; because the same can be done with Cnf{Freeze,Thaw}Bool(), those are also moved out of the system code with this commit.) Color integers were being OR'ed with 0x80000000 in some places for two distinct purposes: One, to indicate use of a default color in glxFillMesh(); this has been replaced by use of the .UseDefault() method. Two, to indicate to TextWindow::Printf() that the format argument of a "%Bp"/"%Fp" specifier is an RGB color rather than a color "code" from TextWindow::bgColors[] or TextWindow::fgColors[] (as the specifier can accept either); instead, we define a new flag "z" (as in "%Bz" or "%Fz") to indicate an RGBcolor pointer, leaving "%Bp"/"%Fp" to indicate a color code exclusively. (This also allows TextWindow::meta[][].bg to be a char instead of an int, partly compensating for the new .bgRgb field added immediately after.) In array declarations, RGB colors could previously be specified as 0 (often in a terminating element). As that no longer works, we define NULL_COLOR, which serves much the same purpose for RgbColor variables as NULL serves for pointers.
