Multisampling on pixmaps?

Hi all,

I'm trying to get the multisampling feature applied to a pixmap that is being written into the GPU with glDrawPixels(). I've seen it work with vector graphics, but no results so far with pixmaps. Is this possible?

Some background: atm I'm using a GeForce 6150 under Suse 10.1 with Nvidia driver 1.0-8762. I need to scale down TGA pics and want the result filtered to get rid of artefacts. I first tried the convolution filter technique, but that dropped bandwith to 6 FPS or so.

Thanks!
Robert
