Was getting segfaults near here with another patch since removed from the branch.
Moving these assignments after the memfree means they still have
useful data when debugging a crash in memfree.
Allows distancing users from the internal "elem" member.
Add Get() and operator[].
Replace direct references to elem.
Make elem and elemsAllocated private in IdList/List.
In other words, Ctrl inverts the normal action of LMB. It is already
possible to deselect entities through the context menu, but that
can be very awkward on laptop touchpads with a crowded sketch; with
Ctrl, a misclick is easily corrected without moving cursor at all.
This means that automatically added H/V constraints now will never
cause the sketch to become overconstrained, which currently makes
that feature almost unusable.
It makes no sense to solve by substitution (therefore weakening rank
check) in SolveRank(), since that's the whole point of SolveRank().
In addition, because SolveRank() is currently always called right
after AddConstraint(), forceDofCheck would always be true anyway.
In addition, it makes no sense to have TestRankForGroup() dependent
on the result of the previous solve. (For SolveGroup(), solving by
substitution after we know that rank test succeeds makes dragging
points much faster.)
Clarify the name of the command, as the old name is not strictly
correct. E.g. consider a vertical line with a midpoint constraint to
origin has 1 DOF, but 2 highlights are shown. Conversely, a single
datum point has 2 DOF, but 1 highlight is shown.
Supported metric units: km, m, cm, mm, µm, nm.
Supported USCS units: in, mil, µin.
Also, use the newly introduced unit formatting machinery in tools for
measuring perimeter, area and volume, so that e.g. volume is not
displayed in millions of cubic millimeters.
It's not very obvious if the extrusion failed because in a later
group, the solid (by default) uses a very dark gray color that blends
into the black background.
This needs to be done separately because, while we already warn on
broken polygons in workplanes, many more groups can be extruded, e.g.
the canonical way (for now) to mirror a group is to use a rotation,
and that doesn't get checked for closed contour, since most rotations
won't get extruded.
MSVC has a long history of value initialization bugs, and this one is
no exception. In this case, when some MSVC versions (at least up to
2013) are instructed to value-initialize a non-POD class with
a compiler generated non-trivial constructor, it does not zero out
the POD members.
Its only use was in a context where it was completely equivalent to
MemFree, so just use that instead, and keep the temporary heap as
purely an arena allocator, that could use something like bump
pointer.
