[Gdal-dev] how to draw images on Windows

[Ben Discoe]

Just as a point of reference, the open-source application VTBuilder, in the
free VTP software, uses exactly this approach to read GDAL files and render
them as DIBSections on Windows, and has been available for years.

And yes, it is "fast as snot" on Win32  :)

The frustrating thing is on Linux, there are no DIBSections so it is
painfully slow to scroll around large images...
