See issue #4008.
The bug in cacheimagedata.cc was preventing correct cached thumbnail
loading, asking for a full processing at each loading of the directory.
The behaviour has changed slightly, so that clicking the menu item now resets
to the default processing profile specified in the preferences. If this
involves calling the custom profile builder, the behaviour is the same as
before. But this is a bit more general, in that it might also simply reapply
the static default profile, or regenerate the dynamic one (depending on the
user's settings)
This new slider in the White Balance tools allows to alter the computation of
the "auto white balance" by "biasing" it towards warmer or cooler
temperatures. The bias is expressed as a percentage of the computed
temperature, so that the resuling temperature is given by
"computedTemp + computedTemp * bias".
