Suggestion: make available the set of filters in p5js (currently THRESHOLD, GRAY, OPAQUE, INVERT, POSTERIZE, BLUR, ERODE, DILATE) as shaders (with the same names), so that users can more easily port sketches between default and WEBGL renderers.

USE-CASE: Student has performance problems in sketch using filters. Instructor would like to suggest WEBGL, but the filter doesn't exist as a shader (or is not easily found).

Another option would be to have the filter call actually work in WEBGL by loading/invoking the correct shader automatically.

Most appropriate sub-area of p5.js?
