Microsoft defines an RGB() macro that at one point was compatible with our
version (returning a packed integer containing 8-bit red, green and blue
channels), but is no longer, and the incompatibility led to an awkward
situation in w32main.cpp where we had to restore Microsoft's form of the
macro in order for the commctrl.h header to compile. By renaming the macro
to RGBi()---analogous to the RGBf() macro we already define---we avoid the
hassle entirely.
The libslvs library and CDemo program can now be built by Autotools. A few
code changes were needed for this: C++ comments in C code had to be
converted, constraint.cpp required some massaging, and fltkutil.cpp needed
a stub for InitHeaps().
Place a pre-built copy of generated source files in src/built/, so that
users building SolveSpace from Git without the tools or setup necessary to
generate these can still complete the process.
Makefile.msvc: Use slashes consistently, and added rules to copy files from
src/built/ if needed
configure.ac: Check for presence of src/built/ at configure time
src/Makefile.am: Handle the generated *.table.h files together with
icon*.h; updated the source-generation rules so that the files are created
in builddir, not srcdir; added rules to copy files from src/built/ if
needed
The SolveSpace top-level directory was getting a bit cluttered, so
following the example of numerous other free-software projects, we move the
main application source into a subdirectory and adjust the build systems
accordingly.
Also, got rid of the obj/ directory in favor of creating it on the fly in
Makefile.msvc.
