* Hardware mouse cursor, drawn and managed (e.g. you provide coordinates, the card does the rest)
* Bitblt (for "''BIT'' BLock''BL''ock Transfer''T''ransfer") can be used for screen-to-screen memory copy like windowswindow moving, scrolling, etc. You provide from and to boxes and the card does the rest. Some might know this as the "rasterop" or remember the hardware "blitter" in Amiga computers.
* Tiles. You enter a small NxN dataset (usually a bitmap of between 8x8 and 32x32), a foreground color and a mixing style plus some coordinates and the card "paints" the area with the given pattern. That can be handy to render Win95-like backgrounds (tiled ones) or even to draw fonts quickly.
