Improved image interpolation and sampling

[uanpis]

BeeRef currently only supports nearest neighbor interpolation / sampling.
This causes quantization errors when images are scaled to a small size:

In this example the fine line art details cause the scaled down version to look noisy.

It would be nice to have better interpolation / sampling methods to avoid this kind of issue.

still hoping for this to get integrated.
