My first OpenGL shader! Momma will be so proud! This shader implements the software renderer mask semantics where the source pixel is multiplied by the color and alpha modulation values and then any pixel with non-zero alpha is fully opaque. The OpenGL renderer on Mac OS X now passes all the automated render tests! :)

pixels don't need to be dynamically allocated Added a dump_screen() function to assist with test failure diagnosis

SDL_RenderReadPixels() needs to flush asynchronous operations before it reads. The semantics are that it reads the back buffer, and those pixels may not be available once SDL_RenderPresent() has happened.

Support for UTF-8 text input has been added.

1. SDL_RenderPresent() call has been added after each test to be sure, that all graphics output is flushed in case if it was asynchronous. 2. After each renderer test window recreation has been added.

Output last SDL error in case of test was failed.

RenderReadPixels and RenderWritePixels now work properly.

Deinitialization fixes, in case if QNXGF driver is not initialized properly.

Added support for generic getopt() function instead of getopt_long(). Because not all platforms have getopt_long().

Support for RendererReadPixels and RendererWritePixels has been added to photon renderer.
