Lots of mostly cosmetic cleanups to GL2 paint engine
* Move most of drawPixmaps to private
* Move most of stroke to private
* Remove dead code: context()
* Make optimiseForBrushTransform use xform type
* Use GLuint for uniform location
* Rename lastTexture -> lastTextureUsed
* Move qopengl2paintengine_cleanup_vectorpath to private
* Re-ordered declarations in header
* Remove dead temporaryTransform
* Rename use_system_clip -> useSystemClip
