#5 Oversampled bitmaps don't display.

[Jason McGuiness]

When oversampling levels over 4 are used, the fractal, when
re-loaded doesn't display. The fractal, if saved or rendered and
saved appears to be fine in the PNG. If such an versampled fractal is
"reset" then it also fails to display in the pane.

Apparently this is a bug in the "::StretchDIBits(....)" function call in
Win2000, WinXP (probably WinNT & Win9X too).

Well - modified to implement my own "StretchDiBits(..)" functionality, that
is called if the Windoze variant fails. Mine is *much* slower, so the screen
update frequency is reduced by over 20 times and in proportion to the
oversampling level.
