During drawing, the depsgrah was tagged to update and this produced a full copy of the datablock. This tag was done in order to get the right data in drawing engine, but this added a great overhead while drawing and the response of the pen was not good.
Now, the depsgraph is not tagged and the drawing engine uses the original copy data of the buffer datablock. This is not a problem because only can draw in one window at time.
- Poly build now uses a new gizmo for pre-selection
which has the same behavior as loop-cut.
This replaces hack where mouse-move set the active element
which was no longer working properly because of missing
depsgraph updates.
- Multi-object support for poly-build.
- Support for deformed cage.
- Fix error where changing active object wasn't properly
refreshing the preselect gizmo (for loopcut too).
Currently holding Alt to select non-boundary element's isn't working.
I don't even know why this operator was ever made to work in object mode.
That said, since it does, we should have different options for it
(or rather, always do all faces for it).
They way Blender handles vertical alignment is very buggy:
- Top-Base: It works perfectly.
- Bottom: It is actually bottom-baseline,
and it fails when line size is != 1.0 when working with text boxes.
- Top: Poorly implemented, it should use font's ascent
(recommended distance from baseline),
so it has room for accents,
but it's not one line distance far from the origin (as it is now).
- Center: Poorly implemented.
This is tricky since there is no silver bullet.
To clear this situation I created a new option (Bottom-Baseline),
and addressed the issues above.
I'm getting the ascent and descent from freetype2,
and use this for padding above/below the text.
Also for vertically centering the text.
Changes from reviewer (Dalai Felinto):
* pep8.
* Skip meshes that come from libraries.
* `Copy Mirrored UV coords > Copy Mirrored UV Coords`.
* Remove mesh(es) from warnings, report mesh or meshes based on number.
