test case

When glDrawBuffers write to front/back buffer and DRAW_BUFFER0 simultaneously, front buffer will be incorrect that every pixel is white.
If glDrawBuffers only write to front/back buffer, it is OK.

The test program has a bug:  GL_DRAW_BUFFERn is not a legal value for glDrawBuffers() or glReadBuffer().  GL_COLOR_ATTACHMENTn_EXT would be the right value.  Though, I think you'll need to create some FBOs for that to work (and not generate a different GL error).

Mass version move, cvs -> git
