 /*
 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
