Davis King 03873a659b Added a cast to avoid a compiler warning.

Davis King c5387bca58 Changed code around a little to avoid problems in gcc when used with mingw. One of the 
problems was that assign_pixel() would sometimes give the wrong output when optimizations
were enabled.  This seems to be a bug in mingw's gcc and these code changes avoid triggering
it.
