Ok, I guess it's just more complicated then that. Just added some debug log to
print the extents.

gst-launch-1.0 videotestsrc ! video/x-raw,width=1280,height=720 ! textoverlay
font-desc='Bitstream Charter, 72' text='<b><i>g</i></b>' ! ximagesink

Gives me, Extents of "<b><i>g</i></b>" is ink (-3, 47) 55x68 and logical (0, 0)
50x117

Regardless how big you make the surface, the left part of the g will always be
clipped unless you also translate the matrix the opposite way. Just doing that
miss-align the text, so we have to compensate when doing the placement.
ink_rect.width though always seems sufficient to fit the text.
