[OpenSmalltalk/opensmalltalk-vm] Fix display corruption when using the Metal backend (#410)

 

Fix display corruption when using the Metal backend on a Mac with Retina Display.

The display corruption was caused by a mismatch between the Form resolution, and the texture size. This ended with a wrong stride for the texture data uploads, which translated to graphics glitches.
