* Input Parameters:
* wnd - The window structure reference
* rect - The location to be copied
* plane - Specifies the color plane to get from.
* dest - The location to copy the memory region
* deststride - The width, in bytes, the the dest memory
*
* Input Parameters:
* hwnd - The window handle
* rect - The location to be filled
* color - The color to use in the fill
*
* Return:
* OK on success; ERROR on failure with errno set appropriately
