Problem to solve

A very common, necessity on Gamedev is the post-processing of pixels. This enables the creation of special effects, for example:

• Reflections
• Refractions
• Fog
• Lightenings and explosions

This is done via first rendering elements of a game and using the result as an input (texture) of a fragment shader.

That can be done in a succession, resulting in an effective pipeline of fragment shaders.

Proposal

• Introduce a way to dynamically preload fragment programs
• Introduce an API represent shader effects (with type-safe inputs (uniforms/textures))
• Apply Effects to Cameras
• Refactor layer API to prevent pipeline re-rendering
