Georges Basile Stavracas Neto 49653b0b0a clutter/blur: Select a better n_steps ... The n_steps variable corresponds to the number of *pairs* of texture lookups that the blur shader does. For example, when n_steps = 1, the for-loop reads 1 pixel before and 1 pixel after the current one. Our blur shader is heavily inspired in WebRender's blur shader, the biggest difference being that we calculate the gaussian samples in the fragment shader itself, and not in the vertex shader. (This could be an improvement in performance for the future though!) WebRender's blur shader calculates n_steps differently than what we currently do, though. It calculates n_step in such a way that at least 2 steps are performed for evey non-zero sigma value.
