Feature Request: HDR support!

[AnyOldName3]

On systems with floating-point render targets (i.e. the GPU does lighting calculations in floating point and saves the result as floating point) it's fairly easy to add HDR support after the fact, as you can just change how the floating point numbers are converted to integers. The Wii and GameCube, however, do a huge amount of their graphics work in integer format, so it's likely that the final render result will be a number corresponding to exactly to the integer the screen wants, making it hard/impossible to change the conversion after the fact.
