Buffers, heap memory, user memory and DIBs will have their own
locations. This field specifies which location is used when the surface
is mapped.

include: There is no need to duplicate CLSID_DirectMusicAudioPathConfig as CLSID_DirectMusicAudioPath.

CLSID_DirectMusicAudioPath is private to Wine and produces the confusion
between the COM objects DirectMusicAudioPath and
DirectMusicAudioPathConfig. But those are totally different things.

winemac: For ChangeDisplaySettingsEx(), if caller didn't specify, prefer non-interlaced and unstretched modes.

When originalDisplayModes has entries, the app is active.  When the app is
active, latentDisplayModes is empty.

We only care if we have changed the mode and we're changing it back to its
original.  Even if the current mode matches the target mode, we may still
need to release the displays and clear the entry from originalDisplayModes.

winemac: Don't assume the current display mode is the original if we don't have the displays captured.

Another process may have changed the display mode before we queried the
current mode, so we may be seeing a non-original mode.

originalDisplayModes should be used when active, empty when inactive.
latentDisplayModes is used when inactive, empty when active.

The count of entries in originalDisplayModes is used to test whether the
process has the displays captured so adding entries when inactive would give
incorrect results.  This could have led us to mistakenly change the display
mode when we don't have the displays captured.
