Graph Region: Address overflow issue using GL2ES3 integer indices (WIP...); Ease GLArrayData* buffer growth.

Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor.
Region.max_indices is computed in this regard and used in Region.addOutlineShape().
TODO: If exceeding max_indices, the code path needs some work.

Buffer growth is eased via GLArrayData using its golden growth ratio
and manually triggering growth before processing all triangles in Region.addOutlineShape().

+++

TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.
