This is a convenience function for creating a solid fill source material from the given color using unsigned bytes for each component.
Latest drawing apis all take an explicit CoglPipeline argument so this stack of CoglMaterials shouldn't be
used.
This color will be used for any subsequent drawing operation.
The value for each component is an unsigned byte in the range between 0 and 255.
