This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Add 'G_draw' for all draw manager globals,
avoids adding extern to each file.
Connection between `ts` and `globals_ubo` wasn't obvious,
now called `G_draw.block` & `G_draw.block_ubo`.
This now only upload data per loops to the GPU, making use of index buffer
to draw polygon. This make use of the vertex cache, speed up renders
and saves a lot of vram.
Update performance is also slightly faster and can even be improved further
by updating only uvs or vcol independently.
This commits breaks texture paint batches. It will be added back in another
commit.
In 2.79 hiding works in paint modes with selection enabled,
so it is a missing feature. This implements it in texture
paint overlays and in workbench base shading.

* Fixes vertices with bad coloring. Now vertices draw with depth write so
they occlude the underlying face geom overlay, avoiding double drawing the
vertex.
* Decrease the z_offset of edges so they don't poke too much through
geometry. Also delete this offset in ortho view.
* Add zoffset to active and selected vertices so they always draw on top
if they overlap a non selected vertex.
* Fix alpha of edge_fix in vertex selection mode
This decouple the vertex display from the face+edges.
This is to reduce the number of triangles required to fix the edges
artifacts (aliasing) and increase viewport reactivity when not actively
navigating (ie. mouse scroll).
Also it makes all vertices visible (not cut-off) even when navigating.
However it makes the navigation drawing a bit slower because it has to
render twice.
Also add a depth bias to the wires to avoid depth fighting when previewing
final mesh (modifiers applied).
This commit make the Xray option for the wireframe different from the other
shading mode. This makes it possible to rapidly switch between wireframe +
Xray and Solid mode without Xray.
Xray alpha is also decoupled.
Both variables are duplicated and exposed separately through RNA.
This makes the Edit Mesh display settings common to all objects. They can
also be set differently per viewport.
Modifying extra data (seams, sharp edges etc...) will no longer set them
automaticaly visible.
Bumping version because we need to force set all extra draw options for
older files.
This adds existing behavior from calc_weightpaint_vert_array
that was missing from the new rendering code:
- No selected Vertex Group displays as a solid pink color.
- Zero weight displays as alert color depending on Options.
- Multipaint mode correctly displays collective weight.
In order to properly implement this variety, a data structure
holding all relevant parameters is introduced.

We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.
To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.
Do note that we force showing the face dot if we are in face select mode
but faces and edges overlays are disable to not loose the selected faces
entirely.
This mimics the behaviour of the old wireframe mode. When in Xray mode,
don't use the limit selection to visible option.
Also hide the option if Xray is enabled.
