[PATCH] Fix messed up display in GTK2

[subsurface at henrik.synth.no]

From: Henrik Brautaset Aronsen <subsurface at henrik.synth.no>

Commit 0323cb3741caa1e0a234815999b0516d2e75b0f1 ("Prepare to
compile with gtk-3") does bad things to Subsurface on MacOSX,
at least on GTK2.   The whole window looks messed up.
