Rename all the classes that are not exported to application to 'Internal'
Fix the fact that back-facing surfaces were invisible.
Progress with non-postprocessed OIT.
Status: compiles, but fails to work on both Adreno and Mali. Crashes the app (Adreno) or the whole system (Mali)
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: more bugfixes
OIT: lots of progress on all fronts. Still a few bugs to solve though!
