Post-processing goodness #3
Description
There is a shader called post_processing_fragment_shader that's just waiting for some sweet post-processing action.
After all blocks are rendered, the entire screen is passed through that shader, which lets you access the normal vector, depth and color and each pixel (u_normal, u_color and u_depth) and outputs the final color that is shown on the screen. I recommend using the linearized depth value which is in the nice range of [0,1], instead of u_depth which is.. complicated.
So maybe implement some cool depth of field?

Or maybe some nice bloom?

Or some sweet sweet SSAO?
