Detailed Description

Offscreen FBO with colour, view-normal and depth attachments.

Used to implement the engine's "internal resolution" pixelation effect. Render the scene at a small size (e.g. 320x240) into the RenderTarget, then BlitNearest() it into the window framebuffer. The non-filtered upscale produces crisp PSX-era chunky pixels.

The second colour attachment receives view-space normals encoded as N*0.5+0.5 (RGBA8) so the outline post-pass can do depth+normal edge detection. Depth is a sampleable texture rather than a renderbuffer for the same reason.
