generators: Force even base image dimensions for fractional HiDPI sizes
In case a dimension of the base image is not even and fractional HiDPI
size is to be generated, the resulting image size computes to a non-integer
values. Rounding in browsers may vary so let's stick with safe values and
force even base image dimensions. This may result in slight crop applied
before resize, generally imperceptible.
Tested on Chromium 69 and Firefox 52.
