fdo#74702 Move BitmapEx drawing code to seperate functions

New virtual functions DrawTransformBitmapExDirect() and
TransformReduceBitmapExTargetRange(). Printers cannot do either of
these things so I make it a noop in the Printer class, Window and
VirtualDevice will continue to work as intended.

I have documented these functions in OutputDevice.

Also made some small formatting changes to print.hxx to align tabs.
