On further testing I found that these are actually 2 separate problems. The
problem with the drawing rectangle was identified in the last email. When I
patched the drawing rectangle state upload back into my local code, that problem
was fixed but the problem with alpha blending still exists. I guess I'll have
to do another bisect tonight to find the source of this.
