Hi, I'm proposing a solution to lift the limitation you mentioned in the README that multiple Gabor patches could not be presented superimposed. First, the Gaussian envelope could be saved as the alpha channel so that the patch becomes semi-transparent. Second, compared to writing GLSL shaders that specifically draw multiple Gabor patches, it is much easier to draw only one patch at a time and save it as an image, then draw multiple semi-transparent patches on a regular 2D canvas or simply on the web page and they are superimposed.

I have created a Garborium-like demo (source). It uses gl.readPixels() to read back the pixel data of the Gabor and then draw it multiple times on a regular canvas.
