View, cell view, cell content view. Even in a quick hack, at least the 
cell content view would need to be passed a shape it would have to clip 
itself to... ugly.

We would need to draw (= put into the display list/s) all the general 
clip vobs before each vob that needs general clipping.

OTOH, we could have a call from the generally clipped vob asking the 
coorder to put all the necessary general clipping into its list. Then, 
only the vobs that really want clipping would get it-- i.e., no connections.

The size of a texel is given to freetype? Or, the font size in texels? 
In the latter case, again: is it height that is specified (in texels), 
or width, or both, or something else?
