This commit possibly fixes the T58938.
The crash happens when a shader that is created in a rendering context is deleted and another shader with the same name/program of the deleted one is created in the same context and used in another context.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
Some old AMD drivers crash when a vbo with stride 1 is used a few times.
I have not found a real solution to this problem. So the solution was to use a vbo with stride 4 (which in theory is less efficient and takes up more memory space).
Almost every pulldown menu and popover has a little dropdown arrow shape.
Unfortunately it is a bit wonky. The top of the right side of it is wider than the top of the left side. And both sides are narrower at the bottom than the top. It might be hard to see, but this image should help:

The patch fixes the symmetry of the shape while keeping the weight as similar as possible. In the following image you can see the outline of the current version in red and this new version in green.

With patch applied the arrow looks perfect:

There is still work needed to be done from multires side to fully
support smooth shading. So can't just always have smooth shading.
Roll back to a proper code in GPU side, the rest will be handled
from CCG side.
The multires sculpt drawing was a not working in smooth mode.
Also hidding was not supported by the wireframe overlay and flat shaded
faces.
Codewise it is cleaner and index buffers are only updated if the
smoothing changes.
The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
test reliably)
This includes a bit of cleanup in gpu_buffers.c.
This will effectively make the AA passes thicker in some cases but it is
required for better AA on wireframes. The trick is to occlude the wire
passes so that they do not output fragment that could be behind actual
geometry.
Values outside the 0..1 range produce negative colors, so now clamp to that
range everywhere. Also fixes improper handling of hue > 2.0 in some places.
Needed to fix T61196, supporting clipped back-buffer in the 3D view
which is done outside the draw module.
It was also inconvenient having DRW_shader_* versions of GPU_shader_*
API calls.
- Clipping distances are now supported as a shader configuration
for builtin shaders.
- Add shader config argument when accessing builtin shaders.
- Move GPU_shader_create_from_arrays() from DRW to GPU.
This is work in progress. Look is not final.
This align data VBO data structure used for edti cage drawing to the one
use for normal drawing.
We no longer use barycentric coords to draw the lines an just rasterize
line primitives for edge drawing. This is a bit slower than using the
previous fast method but faster than the "correct" (edge artifact free)
method. This also make the code way simpler.
This also makes it possible to reuse possible and normal vbos used for
shading if the edit cage matches the
This also touches the UV batch code to share as much render data as
possible. The code also prepare for edit cage "modified" drawing cage (with
modifier applied) but is not enabled since selection and operators does not
work with modified cage yet.
