stephena b200260d85 Huge speedup in OpenGL rendering, by only updating part of the texture ...

instead of the entire area.  This fixes the speed regression from 3.6,
since the main TIA texture is now larger than before.  Previously it
was 160 pixels wide out of 256 total (rounded to power of two), now
it's 560 wide out of 1024 total.  In 3.6 it was updating a buffer 256
pixels wide, in the latest beta releases it was sending 4 times as
much data (256 -> 1024).  Now it sends only 160/560.  Similar
improvements happened with the height as well (210 lines vs 256).
On my test systems at least, this is an extremely large win,
resulting in similar speeds as 3.6 even though we've moved to a 32-bit
framebuffer.

Bumped version # for next beta release.

Pushed release date to June 1, to make absolutely sure I have
everything fixed and ready to go.
