WEBP_REDUCE_SIZE was introduced to bring down the library size by
removing cropping and scaling support. Previously WebPPictureView() was
only used with these two, but in
ec178f2c Add progress hook granularity in lossless
an additional use was added in VP8LEncodeStream() when extra side
configurations are used in crunch mode (-mt, quality == 100 & method ==
6 or quality >= 75 & method == 5 with a palette present currently).
WebPPictureView() and, for coherency, WebPPictureIsView() are
restored in this configuration to avoid affecting the general encode
path.
Previously WebPPictureView() was assumed to always succeed in these
cases which could result in crashes with WEBP_REDUCE_SIZE defined.
