Remove GL or GLSL from names of subclasses. Make nearly all subclasses nested either in FP class or its onMakeProgramImpl() function. Make onSetData private rather than protected. Remove unused INHERITED typedefs. Embrace idea that Impl is part of FP private implementation: direct member access rather than getters and no GenKey pattern. Other random consistency updates, modernatizations, stylistic changes.
