bitfield conversion warnings
As said in !54 (merged) , I ran into several warning regarding bitfield conversions while compiling on Windows with clang-cl, such as:
../src/panel/dzl-dock-stack.c(245,15): warning: implicit truncation from 'int' to bit-field changes value from 3 to -1 [-Wbitfield-constant-conversion]
priv->style = DZL_TAB_BOTH;
^ ~~~~~~~~~~~~
../src/panel/dzl-dock-stack.c(246,14): warning: implicit truncation from 'int' to bit-field changes value from 2 to -2 [-Wbitfield-constant-conversion]
priv->edge = GTK_POS_TOP;
^ ~~~~~~~~~~~
These probably need to be looked at.
