Get background_opacity working, at the cost of breaking negative z-index image rendering.
...
Image rendering will need to use an FBO since OpenGL cannot do proper alpha compositing.
As a first step, the interleaved shaders now generate premultiplied colors as opengl can only alpha blend pre-multipled colors

Workaround to get graphics working on Apple's buggy products
...
Apparently some macOS OpenGL drivers cannot handle using a VAO with
attributes that have different divisors/apply to different shaders. So
use a separate VAO for graphics rendering. This is a small performance hit,
but is the price of supporting substandard computers.
