Brian Salomon 201700fa86 Initial version of rescaling async readback API 
This is implemented at backend-neutral level and so misses some
opportunities to reduce the number of passes in the GPU backend.

Filter quality is interpreted as:
none - single nearest neighbor resampling
low - chain of bilinear resamplings. 2x up/down except for one
step which may be smaller than 2x.
medium - same as low
high - when both scale factors are up then same as low but with bicubic
filtering rather than linear. Otherwise, same as low.

Bug: skia:8962
