[mapserver-dev] drop shadow for labels

I agree this is a regression issue that should be fixed.
But should we also need to deprecate SHADOWCOLOR and SHADOWSIZE or removing
that support in the code was also a regression? I don't see in the
documentation that SHADOWCOLOR and SHADOWSIZE are no more supported and the
migration guide doesn't mention a compatible solution either.
We should also make OFFSET as a bindable attribute, since SHADOWSIZE was
also bindable.
Best regards,
Tamas
