In order to allow GLSL Cross Compilation across platforms, expose in Python the `GPUShaderCreateInfo` strategy as detailed in https://wiki.blender.org/wiki/EEVEE_%26_Viewport/GPU_Module/GLSL_Cross_Compilation The new features can be listed as follows: ``` >>> gpu.types.GPUShaderCreateInfo. define( fragment_out( fragment_source( push_constant( sampler( typedef_source( uniform_buf( vertex_in( vertex_out( vertex_source( >>> gpu.types.GPUStageInterfaceInfo. flat( name no_perspective( smooth( >>> gpu.shader.create_from_info( ``` Reviewed By: fclem, campbellbarton Differential Revision: https://developer.blender.org/D14497
