GPUShaderCreateInfo for interface abstraction 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.

#ifndef USE_GPU_SHADER_CREATE_INFO
GPU: Add Polyline shader (wide line emulation) This new shader is able to emulate smooth wide lines drawing using a geometry shader. This shader needs viewportSize and lineWidth uniforms to be set. There is multiple variants to replace the usage of wide lines for most shaders. This patch only fix the gizmo_types files and the navigation gizmo. Other areas could be fixed afterward, I just limited the patch size. Fix T57570. Reviewed By: billreynish Differential Revision: https://developer.blender.org/D7487

uniform float lineWidth;
Fix T81827: MacOS lines that should be thick are green instead The issue was the use of alpha values of 0 when there were no blending enabled. This patch just disables the smoothing of the wires in this case.
