There was no selection flushing when faces or verts were selected, this allowed incorrect selection states like selected face with unselected vertices.
add flush commands to paintface_flush_flags() and paintvert_flush_flags()
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.
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
1. Two new boolean options have been added to the operator: "deselect"
and "toggle".
2. The previous behavior of "extend" (toggling the selection) has
been moved to the "toggle" option.
3. "extend" now only extends the selection, it never deselects.
4. "deselect" is pretty self-explanatory: it deselects (i.e. opposite
of extend).
5. The built-in keymap has been changed to use "toggle" where
"extend" was used before for this operator, to maintain the
previous behavior in the default keymap.
In short, this works towards making "extend" and "deselect" fully
consistent across all selection tools (adding to and removing from
selection, respectively), but still preserves the old behavior
as well.
(Patch reviewed by Brecht.)
These changes are to make the bmesh api more consistent and easier to learn, grouping similar functions which is convenient for autocomplete.
This uses similar convention to RNA.
* use face/loop/edge/vert as a prefix for functions.
* use 'elem' as a prefix too for functions that can take any type with a BMHeader.
* changed from camel case to underscore separated (like RNA).
- some merges added lines in multiple times
- removed some NULL checks that were only in bmesh
- enable cycles by default (was disabled because it used not to work)
- make formatting match
