Fix positioning errors with category ticks...

Fix positioning errors with category ticks Two problems are fixed in this commit: 1) Rounding errors caused by use of int instead of qreal made category axes to be one pixel off 50% of the time. 2) Bar category axes offset was calculated incorrectly, and again with rounding errors stemming from use of int. Also fixed some code style issues in related code. Task-number: QTRD-1920 Reviewed-by: Mika Salmela
