[poppler] Replacing Bresenham in Splash with Bilinear

[Arpit Bansal]

Hi,

I'm  trying to add bilinear sampling algorithm in poppler's splash image rendering. We are not getting best results from the current Bresenham Algorithm. Though the time of conversion is exceptionally fast but current implementation doesn't do a great job with rotated or downscaled images.

Does anyone have any suggestions or advice regarding the same?

Thanks
Arpit
