Distorted Android

Add possibility to create FBOs with combined DEPTH/STENCIL.

Simplify setting up DistortedScreen.

1. Correct some bugs in DistortedRenderState
2. Thus make the Stencil App work
3. New icon for it

Progress with Stencil App; should be working now AFAIK but doesn't.

Beginnings of Stencil App.

Some corrections so that most apps still work on the Android emulator (OpenGL ES 2.0-based)

Merge Transform Feedback

Use Transform Feedback to (optionally) display the Normal vectors.

Dynamic display of bounding rectangles (with coords computed by Vertex Shader and gotten with Transform Feedback) works now.

Major problem: the glMapBufferRange() slows doewn rendering in a major way. Multiblur's FPS:

Nexus5X : 35.4 before -> 12.6 after...

Beginning of support for actual Transform Feedback.

Beginning of support for actual Transform Feedback.

Minor bugfix.

Move from unpacked to packad server-side Vertex attribute buffer.

Make the Feedback APP work again.

Merge remote-tracking branch 'origin/master' into transform-feedback

Some progress with Transform Feedback. Still many bugs all over.

Beginnings of support for DistortedEffects.drawPrivFeedback()

This commit (and reading the OpenGL ES 3.0 spec) pretty conclusively proves that, sadly, Nexus 4's Transform Feedback implementation is incomplete (doesn't work with GL_TRIANGLES primitiveMode)

Progress with TransferFeedback app - introduce two modes: USEPOINTS 'true' or 'false'.

On Nexus5X, it works with 'true' and 'false'. On Nexus 4, it works with 'true', but returns GL_INVALID_OPERATION with 'false'.
