- some fixes to the PP shader interface.

The binding point needs to be part of the ShaderUniforms class because Vulkan will need this value to generate the declaration in the shader source.
There's still one issue here: Since OpenGL has no local render state, the buffer must be bound every time it is used. Once the code is better abstracted this should be moved to a higher level class that knows all associated data and how to set it up.
