Drivers: GFX_*/BeOS
BeOS Allegro supports the following card parameters for the set_gfx_mode() function:

• GFX_TEXT
  This closes any graphic 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_BEOS_FULLSCREEN
  Fullscreen exclusive mode. Supports only resolutions higher or equal to 640x480, and uses hardware acceleration if available.

• GFX_BEOS_FULLSCREEN_SAFE
  Works the same as GFX_FULLSCREEN, but disables acceleration.

• GFX_BEOS_WINDOWED
  Fast windowed mode using the BDirectWindow class. Not all graphics cards support this.
