Patch from Yichao Yu Choqok's TextEdit uses the minimum length of the scrollbar as it's height (through QAbstractScrollArea::minimumSizeHint) and it also sets a hard limit on the height of the editor. These cause two problem: 1. The height of the TextEdit is theme dependent and for a theme that allows short scrollbar (which is perfectly legal), the text box can be too small. 2. When the use specifies a larger font (e.g. 32-72) the TextEditor will not expand along with it leaving only one (or less) visible lines. REVIEW:114022
