Distorted Android

Correct an issue shown by Crashlytics: sometimes it would crash in the library in InternalOutputSurface.setAsOutput() when trying to 'read from null array' mFBOH[].

Fix normals in case of MatrixEffectScale / Shear.
Fix displaying the normal vector.

Fix modifications of normals in VertexEffectScale and VertexEffectShear.

Progress with the Dino.

When blurring or glowing, we need to CLAMP_TO_EDGE the texture - otherwise part of the blur or glow could appear on the other end of the texture.

Improve the Blur App to catch the bug where a small part of the Blur (and Glow) halo gets displayed on the other edge of the surface.

Correct Inflate vectors in Triangles mesh

Improve debugging in DistortedScreen

Correct a subtle bug iin Framebuffer: in recreate(), we need to mark the FBOs as deleted on GPU; otherwise later we might delete them - and when we do, they might belong to another Framebuffer already!

Fix the fact that Distort was rotating normals outside of its region!
