Distorted Android

SSBO: counting of transparent fragments more or less works now. Still the counters are zeroed out in the wrong place - every time we start rendering something to a given Surface, rather than once per frame.

SSBO: more and more works...

SSBO: fix problems with endianness.

SSBO: something is working already, although we still get the 4 bytes back from the shader in reverse order ( so '17'=0x00000011 written by the shader becomes '285212672 = 0x11000000' )

First try at the SSBO (doesn't work - reads in the application don't pick up changes in the shader; crashes.

Up library requirements to OpenGL ES 3.1 (needed for the upcoming GL_SHADER_STORAGE_BUFFER)

New Object Counter class - to count OutputSurfaces lazy way, but keep the counters small (reuse)

Remove debugging.

Initialize MessageSender even if compiling some of the programs fails.

Internal API change around postprocessing.
