Subject: [PATCH] More flexible calculation of tspanDy for tick texts

Using a quarter of the height of a char to compute the vertical offset of tick texts in relation to the actual ticks results in a more accurate positioning of the y axis tick texts. This becomes important if you want to change the tick text font size via CSS.
