add method to change drawing interpolator
...
default interpolator used for drawing text and images is draw.BiLinear
and it's rather slow against e.g. draw.NearestNeighbor
The difference is significant especially on weak hardware
e.g. on raspberry pi zero (ARMv6) drawing short string can be 10-16 times
faster with draw.NearestNeighbor
