OSDraw

void CATWindow::OSDraw ( CATDRAWCONTEXT  drawContext, CATRect *  dirtyRect   ) [protected, virtual] OSDraw() performs the operating system specific drawing. OSDraw() will call back into the window to perform the normal Draw() command, copy the resulting image into a system-dependant image, then perform any system-specific control drawing through PostDraw(). After that, it will display the results to the screen. Parameters: drawContext  - drawing context for the system / window dirtyRect  - the portion of the window to draw, or 0 for all.
