Fix licenses :)
Rename all the classes that are not exported to application to 'Internal'
OIT: fix for 'out of memory' crash on Mali GPUs.
~The thing still does not fully work there - there are still strange flashes in apps that innvolve OIT, for example in 'Triblur'.
OIT: fixes. Everything looks correct now except for the curious return of the 'dancing lower-left corner' small glitch in the 'Transparency' app.
OIT: move towards 4 passes ( clear - build - collapse - render )
