This should have no functional changes.
This reduce the complexity of the shader by only supporting 2 colors.
We never use more than 2 color in practice and this makes usage not require
a UBO.
- Metal uniform array compatibility in DRW module.
- Guard OpenGL-specific workarounds and flushes behind GPU_type_matches_ex API guard. Add further render boundaries for render paths called outside of the main loop.

Improve the nodes' drop shadow by making it scale with the view
and replace the loop for the alpha calculation with something more
explicit.
The amount of drop shadow softness was scaled with the zoom level
and therefore had a fixed screen space size. DPI and UI scale
weren't taken into account either. This patch fixes both issues by
basing the shadow softness on the `widget_unit` that scales correctly
in zoomable views and takes UI scale etc. into account.

This is a first part of the Shader Create Info system could be.
A shader create info provides a way to define shader structure, resources
and interfaces. This makes for a quick way to provide backend agnostic
binding informations while also making shader variations easy to declare.
- Clear source input (only one file). Cleans up the GPU api since we can create a
shader from one descriptor
- Resources and interfaces are generated by the backend (much simpler than parsing).
- Bindings are explicit from position in the array.
- GPUShaderInterface becomes a trivial translation of enums and string copy.
- No external dependency to third party lib.
- Cleaner code, less fragmentation of resources in several libs.
- Easy to modify / extend at runtime.
- no parser involve, very easy to code.
- Does not hold any data, can be static and kept on disc.
- Could hold precompiled bytecode for static shaders.
This also includes a new global dependency system.
GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...).
This patch already migrated several builtin shaders. Other shaders should be migrated
one at a time, and could be done inside master.
There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional
directive for linting shaders to increase turn around time.
What is remaining:
- pyGPU API {T94975}
- Migration of other shaders. This could be a community effort.

This commit improves the scaling of some ui widgets when
zooming by making the radius of the rounded corners
dependent on the element's zoom level.

Somehow, the file from T71329 has an empty curve profile. While that may
be a problem in itself, it's reasonable to avoid asserts or crashes when
loading or drawing such a CurveProfile. This commit just makes sure the
table always has a single vertex, and adds some checks in drawing code.
Passing 4x arguments for the rectangle,
mixed in with round-box radius & color wasn't very readable.
Instead, pass a `rctf` as the first argument to UI box drawing functions.
The new GPU_SHADER_2D_WIDGET_BASE shader allows us to draw
many complex shapes with anti-aliasing.
One thing it can do is draw an opaque rounded rectangle with colors
that differ between its interior and outline.
In order to do the above in a single pass I recently added an "_ex"
version of UI_draw_roundbox that exposes most of that shaders features.
This simplifies interface_draw.c by removing redundancy in the calling
of this shader by using this new uber "_ex" version.

If there was a control point at an extreme position when drawing a curve
profile (in the bottom corner), the fill's trianglulation could fail, giving
a misleading view of the curve. This is because the extra points added to
create a closed shape were exactly on the border of the view.
This commit adds a small margin to those points, so the triangulation
doesn't fail because the line overlaps itself.
Another possible solution is to use a different algorithm to fill
the polygon, such as scanfill, which is used by curve objects.
This seemed simpler, and seems to work fairly robustly.

This patch fixes assert on grid drawing. `for` loops are used instead
of `while` loops to make sure the number of lines is exact. The old
code draws lots of unnecessary lines offscreen. This bug is fixed as
well. See the patch for a comparison without a scissor test.
