Auto Generate High Resolution UIBB.R16

Keep it Funky, Keep it Fresh.  :)
I converted my Python High Res code into C to generate for each unique
resolution a custom high resolution UIBB.R16 file. Naming is like this:
UIBB.1920x1080.R16, so that original is untouched and high res uibb will
only be generated once.
