Only insert the 'Mali r12' FBO queue fix if we actually are running on a Mali GPU with driver version <22. (then FBOQueue=4 - unless we manually overide this down to 1 - else, always 1)
Lower requirements - now only OpenGL ES 3.0 is required; if running on such platform, OIT part of the API ( which is the only one which actually requires 3.1) is switched off.
Correct the Legal notice.
Rename all the classes that are not exported to application to 'Internal'
Correct the same bug for DistortedTextures and DistortedFramebuffers: only mark them for creation when we actually have everything ready, i.e. as the last statement in the constructor.
Hide the FBO_QUEUE thing inside the library. The queue is running internally now, without public setAsOutputFBO() thing (simplifies writing postprocess effects)
a mix of two changes:
1) remove the DistortedInputSurface interface (now every Surface is Input)2) make the OIT SSBO self-adjustable in size
I spoke too soon, the ARM Mali flashing is of course not fixed yet. The previous commit fixed Triblur, but the bug is still reproducible elsewhere (only in the 'postprocessed' apps though).
This commit introduces a circular queue in case of the postprocessing FBOs - with little success though.
Finally properly fix the flashing on ARM Mali T880 GPU.
The flashing is caused by a 'full pipeline flush' (see DarkPhoton, https://www.opengl.org/discussion_boards/showthread.php/200754-Flashes-on-ARM-Mali?p=1291679&viewfull=1#post1291679 ). In order to combat it, first introduce the possibility that a single DistortedOutputSurface is backed up by more than one FBO. Then make DistortedScreen be derived from DistortedFramebuffer (which itself is derived from DistortedOutputSurface) and make it contain 3 FBOs, render to them in a circular queue fashion, and blit from a given FBO to the system FBO. The 'more than 1 intermediate FBO' queue prevents the pipeline flush....
Port all the 'non-controversial' changes from order-independent-transparency branch.
Fixes ported from the 'OIT' branch:
- remove counting of transparent pixels- various fixes for the Mali GPU
Introduce possibility that an OutputSurface is backed up by a larger texture than necessary and the 'cloneSize()' method.
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)
1) Fix for the last fix in Framebuffer2) in RenderState, reset everything to a known state (rather than mark as unknown)
Fix in Framebuffer
All knowledge about Postporcessing moved to the respective Effect classes.
Progress with support for Effect classes.
