Specifies whether the background bitmap should be tiled.
__property bool TileBackground;
Description
Use TileBackground to specify whether the background bitmap should be tiled on the surface. If it is set to true, Ivory Draw tiles the bitmap on the surface like a wallpaper. Otherwise, it stretches the background bitmap so it fills the whole surface. The new background doesn't take effect automatically; you must call Paint to repaint the surface with the new background. TileBackground only has effect if DrawBackground is set to true. Otherwise, it is not used. The default value for TileBackground is false.
