In comments made by a tester on rB17b89f6dacba007bf, it seems that baking of the spray maps would be useful. This commit adds that capability. Both the spray map and its inverse are baked out in this change, for maximum convenience and to avoid assuming what the user wants. Differential Revision: https://developer.blender.org/D8470
