GPUShaderCreateInfo is a new API to cross compile GLSL shaders to OpenGL3/4 and Vulkan.
The API is currently only available in C/CPP.

This task is to enable the API in python. As complex structures are used we should come up with a design.
For example we could use python internal data-types (dict,list,str) Or we could wrap the API in RNA structs.
The later needs some changes to the RNA system, what is already being discussed.

I see that a lot of work has already gone into this(see below the list). Is this task done? Or is there more work still to do here? (I'm looking for a starter project that'll help me familiarize with the Vulkan API)

@Spundun-Bhatt, yes wasn't aware that the python api was already added. Note that the python example files and documentation might need some examples using the new GPUShaderCreateInfo.
