- Fix: text draw in fonts was slightly too low; it didn't calculate offset
correctly. Now it is aligned to have number characters in center.

- Fix: text clip was too wide, giving errors on extreme zoom in.

- Added boundbox-clipped default text drawing for view2d:

void UI_view2d_text_cache_rectf(View2D *v2d, rctf *rect, char *str)

(Note; also for previous commit, this cache immediately projects, so if
you change view2d while drawing, text is still on correct positions)
