It was check happening when generating menu with available modes
for merge operator, but no checks happened when executing operator.
Since operator could be called from python or shortcut, it was
possible to bypass all the checks.
Selection is specifically so you can continuously fill in holes by tapping the Fkey.
Similar functionality to the F2 addon, however the mouse location isn't used.
besides performance in some cases.
* DAG_scene_sort is now removed and replaced by DAG_relations_tag_update in
most cases. This will clear the dependency graph, and only rebuild it right
before it's needed again when the scene is re-evaluated.
This is done because DAG_scene_sort is slow when called many times from
python operators. Further the scene argument is not needed because most
operations can potentially affect more than the current scene.
* DAG_scene_relations_update will now rebuild the dependency graph if it's not
there yet, and DAG_scene_relations_rebuild will force a rebuild for the rare
cases that need it.
* Remove various places where ob->recalc was set manually. This should go
through DAG_id_tag_update() in nearly all cases instead since this is now
a fast operation. Also removed DAG_ids_flush_update that goes along with
such manual tagging of ob->recalc.
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.
