Like you said in e478f52, performance is still not incredible for the DemoAACircles.
Results on my Linux machine:

  • 1000 circles: 4-5 FPS
  • 500 circles: 8 FPS
  • 100 cirlces: 30 FPS

This is completely expected: the shader is called repeatedly for each circle!

Circles should be drawn only once to a mip-mapped texture and then used at the proper resolution. Color change will be done using tinting like in the current solution.
