It's tricky - OpenGL can zoom images but I don't think
you can shrink them. Hardware to shrink images would
be quite complicated.
You could render it to a texture and draw quads for each
size but the small image would only have GL_NEAREST
filtering and would probably look horrible (though full screen
antialiasing would help with this).
There's an extension to generate mipmaps for a texture
in hardware but it won't work for non-power-of-two textures
and I'm not sure that many cards sup****t it anyway.

PS: What happened to www.delphi3d.net ? I used to use
it all the time to check which cards sup****ted OpenGL
extensions but it's been broken for months.
Are there any other web sites with lists of cards/extensions?
