6a9916d734 WebPRescalerInit: add missing int64_t promotion
large values of x_add and y_add may rollover an int causing a later
assertion to fail in WebPRescalerExportRow due to fxy_scale incorrectly
being set to 0.

fixes:
src/dsp/rescaler.c:178: void WebPRescalerExportRow(WebPRescaler *const):
Assertion `wrk->src_height == wrk->dst_height && wrk->x_add == 1'

8fdaecb09d Disable cross-color when palette is used.
With palette+predictors, cross-color was forced (because of predictors).
No need for cross-color for palettes as R/B==0.
This saves 10 bytes per image that uses palette+predictors.
