 Basic offscreen rendering in two passes. First pass renders the mirrored scene to a separate framebuffer with color and depth attachments, second pass samples from that color attachment for rendering a mirror surface.

 Implements a simple CPU based particle system. Particle data is stored in host memory, updated on the CPU per-frame and synchronized with the device before it's rendered using pre-multiplied alpha.
