On some platforms VK_FORMAT_R8G8B8_* are not supported as vertex buffers. The
obvious workaround for this is to use VK_FORMAT_R8G8B8A8_*. Using unsupported
vertex formats would crash Blender as it is not able to compile the graphics
pipelines that use them.

Known platforms are:

  • NVIDIA Mobile GPUs (Quadro M1000M)
  • AMD Polaris (open source drivers)

This PR adds the initial workings for other unsupported vertex buffer formats we
need to fix in the future.

VKDevice.workarounds.vertex_formats contain booleans if the workaround for
a specific format should be turned on (r8g8b8 = true). VertexFormatConverter can be
used to identify if conversions are needed and perform the conversion.
