Magic Cube

Rename packages

Fix the 6fad862b commit and remove the UI block in a proper way (i.e. the problem was that popping up the Object, Play or Menu windows was impossible while the 'WIN' glow was active)

Properly solve the issue with Qualcomm driver V@331 having buggy UBO size.

Comment eexplaining the recent 'gigaminx ban' on some platforms.

Relax the conditions when we do not support Gigaminx - looks like Adreno 30x has nothing to do with it, just driver version 331.

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....

Bugfix for a crasher

Fix movements of objects - before it really worked only when an object's FOV was about 60 degrees.

Do not block the UI if, for some reason, some of the effects failed to get added to the Queue. Just fail to rotate.

Bugfixes as a result of the Samsung Galaxy J4+ investigation:

1) By default, switch off transform feedback in the main program.
Create a new API 'needTransformFeedback()' to call if someone still needs TF in the main program.
2) lower the default max number of vertex effects to 30....
