I am starting to write some Windows programs that require the display of
(for example) 8-bit images.  Can anyone recommend a fast method to add
scanlines (a row of pixels) to a client area?  I imagine I have to maintain
a bitmap so I can re-paint my window.  Do I perform a SetPixel() for
each pixel into a memory DC viewing a bitmap?

A related question is the issue of palettes.  I have not found any mention
of how to change the palette the GDI uses.  I understand that changing
the palette affects the whole screen, but I can live with that, especially
if I have a 256 color display.  So, how does the palette get manipulated?

Thanks for any help.
