Subject: [PATCH] make all heights in the calendar header to be even

the layout engine has a bug
https://bugreports.qt.io/browse/QTBUG-58307
that if some items have an odd height, some an even height,
the smallest items are resized by half pixel to try to
really center it, breaking rendering
BUG:375318
