Distorted Android

Correct an crash when trying to run a program with no vertex effects.

Another attempt at fixing tthings on early Qualcomm OpenGL ES 3.0 drivers.

The previous version does not work on Adreno 405 driver V@100, present for example in a Asus ZenPad 8.
Revert the packed 'ivec2' UBO in the vertex shader back to a 'std140' ivec4. This comes at a price if bumping into the bug on Qualcomm driver version 331 on Adreno 308 - i.e. Samsung Galaxy J4+ again....

Make the 'Component Associations' UBO (on most devices) twice smaller -
use the 'packed' layout and 'ivec2' in place of 'ivec4'.

This forces us to dynamically probe the 'Stride' - number of 4-byte entities that the UBO's 'ivec4' takes - and correct the already-constructed UniformBlockAssociation objects in case this turns out to be different than the expected 2, i.e. tightly-packed....

Remove UBO from the fragment shader and come back to the default of only 5 concurrent fragment effects. All because UBOs in fragment shader crash on Adreno 510 and Adreno 506.

Introduce another Uniform Block Object. Now we can have much more vertex and fragment effects - up their default number to 100.
