Detailed Description

Subclass of GrGLSLProgramDataManager used to store uniforms for a program in a CPU buffer that can be uploaded to a UBO. This currently assumes uniform layouts that are compatible with Vulkan, Dawn, and D3D12. It could be used more broadly if this aspect was made configurable.
