though the max chunk/payload sizes were checked and would fail the
padded size was being calculated beforehand which could result in a
(harmless) unsigned int overflow warning.

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.

Assertion `wrk->src_height == wrk->dst_height && wrk->x_add == 1'

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.

and PTHREAD_CREATE_JOINABLE (not PTHREAD_CREATE_UNDETACHED) and
internally use HAVE_PTHREAD_PRIO_INHERIT and PTHREAD_CREATE_JOINABLE
(and not HAVE_PTHREAD_CREATE_JOINABLE).
cmake/config.h.in actually had the right variables.
