Pkg.test demo window size doesn't match active area size

[CrashBurnRepeat]

When first starting the demos, there's a discrepancy between the window size and the area GLVisualize is using to do the demo rendering. Resizing the window seems to correct this, but still not sure why this occurs.

Great, you captured and accurately described one of the bugs that where only occasionally turning up and hard to pin down. I have an idea about this and will look into it!

[CrashBurnRepeat]

I should probably mention two things about this issue that I haven't before. The first is that this isn't an intermittent issue for me, this occurs every time I use Scene. The other thing is that this doesn't occur when I generate a figure using glscreen, so if I run this example outside of the Pkg.test environment it runs fine.

[SimonDanisch]

Ah, very good to know! The Pkg.test code is overly fancy, so there is quite a bit of potential for bugs...
