Description
Created by: AmnonOwed
I'm packing data in a texture (PImage) to send to a fragment shader. I'm running into the limitations of the 32bit RGBA format that seems to be the default for every texture in Processing. It's causing banding effects in my output. Switching to floating point textures will most likely solve these problems, because of the increased accuracy.
I have searched high and low (all the forums, the source code, the issue list), but I cannot find a way to use floating points textures in Processing. Is this possible? If not, I would like to post this issue as a feature request.

Research direction
Start by tracing how Processing's PImage textures are created and passed to fragment shaders through its OpenGL path. Determine which floating-point texture formats and supported hardware constraints must be covered. Done would mean a documented, tested way to use floating-point textures without the current 32-bit RGBA limitation.
