Xpra: Ticket #693: scaling rendering is broken with opengl

Not sure when this started, tested with vpx. (found thanks to #692)

The opengl window renders the update only on the top-left portion of the screen which corresponds to the downscaled dimensions. The non-opengl rendering works fine.

Good news: v0.14.x is not affected by this, but trunk r7803 is.

Bisecting by visual inspection (..) using a server running like this:

XPRA_SCALING_HARDCODED=1:3 xpra start :10 --start-child=glxspheres --no-mmap

Hardcoding the scaling to ensure it is enabled, and disabling mmap which bypasses encodings.

So this was caused by #679.

Fixed in r7804: we must paint the screen using the unscaled dimensions!
