 	** GFX_CAPABILITY_SHADING: draw_filled_rect() supports drawing shaded
 	**    rectangles.
-	** GFX_CAPABILITY_PIXMAP_REGISTRY: System provides a pixmap registry. The
-	**    invoking functions will assume that all pixmaps MUST be registered;
-	**    if this flag is not set, it assumes that pixmaps MUST NOT be
-	**    registered. Note that this excludes pointer pixmaps (see below)
-	** GFX_CAPABILITY_POINTER_PIXMAP_REGISTRY: The system provides a pixmap
-	**    registry which mouse pointers have to be registered in explicitly.
-	**    This MUST be used only if the registry is identical to the 'normal' pixmap
-	**    registry. Otherwise, it MUST be handled manually by the driver,
-	**    unless pointer support is disabled completely.
-	** GFX_CAPABILITY_SCALEABLE_PIXMAPS: Pixmap scaling is fully supported.
-	**    If this capability is flag is set, all pixmaps passed to the driver
-	**    will be unscaled.
 	** GFX_CAPABILITY_STIPPLED_LINES: The driver is able to draw stippled lines
 	**    horizontally and vertically (xl = 0 or yl = 0).
-	** GFX_CAPABILITY_KEYTRANSLATE: The driver's input layer automatically
-	**    handles 'shifted' keys (i.e. turning shift-'a' to 'A' etc.).
-	**    Drivers only need to handle this if they desire to support
-	**    non-US keyboard layouts, usually by localisation methods
-	**    provided by the underlying windowing or operating system.
