Describe the bug

I suspect there's a bug in this line:

https://github.com/openrndr/orx/blob/master/orx-fx/src/shaders/glsl/blur/box-blur.frag#L52

I will test it. But I think it should be ++w, otherwise the steps are not regular, and the w variable is unused.

Steps to reproduce the bug

That code is bit messy and w is unused. However the behavior is correct looping using x from WS to WE. There are some remainders of an attempt to support WebGL1 targets that can be taken out.
