It was caused by own mistake by not noticing externtex is used not
only by render engine. Now this function uses pool passed as argument
rather than using R.pool.
- use DummyRNA_NULL_items to replace empty enums.
- replace calloc with malloc in copy_dverts since its copied over after.
- add wmGesture->userdata, so operators that use gestures have somewhere to store their own data (not used yet).
caused by not projecting points behind the perspective view,
even though this worked in 2.64 the values were flipped (rotating direction was reversed and the center point was flipped).
added V3D_PROJ_TEST_CLIP_NEAR, when omitted ED_view3d_project_*** will project points from behind a perspective view plane.
this may introduce bugs which I didn't catch, but they are very easy to identify in a debug build which has asserts to ensure the arrays are valid before use.
in my own test drawing ~98,304 quads - this gave an overall ~16% drawing speedup.
add type checking for element buffers, there was nothing stopping python from passing any element type into an argument when in some cases only verts/edges/faces were expected.
now operator args define which types they support.
like it did before bmesh.
Neither method is perfect, ideally it should do smart detection of UV islands
but without that it's better to disable because it is more difficult to recover
from incorrectly merged UVs than ones that were not merged.
- the resulting selection is now correct
internal details
- bev_rebuild_polygon() now only rebuilds polygons that are attached to a bevel vertex (was rebuilding ALL).
... need to take care we don't leave faces pointing to removed geometry, so far this works fine.
- bev_rebuild_polygon() uses stack memory for <32 size ngons to reduce allocs.
- skip hash lookup when removing bevel verts (use tag instead).
When blending shape key, opening the popup didnt execute anything - making it so pressing a button would update the result even if the value didnt change.
- Rename 'mesh.select_nth' operator menu item 'Every N Number of Verts' to 'Checker Deselect',
since its not just de-selecting verts (works on edges and faces too) and the term 'checker' gives a better description of the result.
- Rename 'mesh.select_by_number_vertices' to 'mesh.select_face_by_sides', since this is a face selection tool, which wasnt obvious from its name.
also remove dissolve by type menu since the option has been removed from the operator and was giving an error.
