Fixed forced pixel format application to surfaces

Browse Source 
Because the actual display mode is always forced to 32 bits color depth,
surfaces that would be created without a pixel format need to be explicitly
set to the emulated display mode's pixel format that the application expects,
rather than letting them use the actual display mode's pixel format.

However, the emulated pixel format was being forced on surface types that aren't
normal surfaces and shouldn't inherit the display mode's pixel format
(e.g. vertex buffers and depth buffers), which prevented some of these surfaces
from being created correctly.
Now the surface type checks are more restrictive.
