Regression test result

Version 1.3.0 introduces a bug with Starcraft 2, where the actual game screens
are rendered mostly upside down. Version 1.2-rc7 (and presumably 1.2 itself)
doesn't have this problem.

I'm currently using an ATI 4870 card with the proprietary drivers, on an x86_64
machine running Debian Sid.

Relevant-looking registry settings are:
"OffScreenRenderingMode"="backbuffer"
"DirectDrawRenderer"="opengl"

This bug (as well as another problem with setting the in-game shader settings
above 'low') does not appear when "OffScreenRenderingMode" is set to "fbo". In
"fbo" mode, however, the majority of screen real-estate is too garbled to be
usable.

Since this is a regression I performed a regression test and the results are
attached. I'll also try to upload a screenshot of the bug.
