O2D: Use cairo_surface_create_similar to make the surfaces for textures instead of always using image surfaces on every platform.
On Windows this would have changed the code from using GDI compositing + image textures to using GDI compositing + GDI textures, but strangely that makes performance much worse. But it turns out that COMPOSITING_TO_IMAGE (i.e., image compositing + image textures) is better than both of the other options.
Improves performance on Linux by 19%-36% (higher resolutions are improved more).
Improves performance on Windows by 6.8%-21% (higher resolutions are improved less).
TEST=loaded O2D on Linux and Windows are compared CPU utilization before and after across various resolutions
BUG=none
