Drivers GFX_*/MacOSX

MacOS X Allegro supports the following card parameters for the set_gfx_mode() function:

GFX_TEXT
This closes any graphics mode previously opened with set_gfx_mode.
GFX_AUTODETECT
Let Allegro pick an appropriate graphics driver.
GFX_AUTODETECT_FULLSCREEN
Autodetects a graphics driver, but will only use fullscreen drivers, failing if these are not available on current platform.
GFX_AUTODETECT_WINDOWED
Same as above, but uses only windowed drivers.
GFX_SAFE
Special driver for when you want to reliably set a graphics mode and don't really care what resolution. See the set_gfx_mode() documentation for details.
GFX_QUARTZ_FULLSCREEN
Fullscreen exclusive mode, using the CGDirectDisplay interface. Supports only resolutions higher or equal to 640x480, and uses hardware acceleration if available.
GFX_QUARTZ_WINDOW
Windowed mode using QuickDraw in a Cocoa window.
