/*
click on the image to choose a colour (maybe draw a line or outline a range of colours?)
works really well. now, how to appy a transform
this approach maps the whole image onto the whole screen.
the texcoords come from the vertex shader?
I suppose that it's necessary to add extra transforms and extract
extra texcoords from the vertex shader
although it'd be possible to use a simplistic shader in this way
and create the scaled textures normally as Fbos
need a tutorial on transforming textures using the GPU
