What would be a higher quality alternative to StretchBlt for drawing an HBITMAP?

I don't want to use GDI+'s DrawImage because of speed i开发者_运维技巧ssues. What other ways are there to draw an image resized with decent quality - at least linear or cubic interpolation?

You can use SetStretchBltMode with the HALFTONE setting, but you'll probably run into the same speed issues that you faced with GDI+ -- smoothing always comes at a cost.
