Text properties apply to characters, so they don't have a natural notion
of "extent" and "boundaries", but Emacs usually invents those notions
when needed by treating any run of characters whose text-property value
is `eq' as one extent.
In the case of the mouse-face property that means you can use (list 'my-face)
on the chunk you want to make sure it's not `eq' to an adjacent chunk.

W.r.t. functions that return the pixel width/height of a string, I guess
you'd presume that the string would be displayed at the leftmost
position on a line, since the width/height of a string will depend on
where it's displayed in the window (which affects the width of TAB
chars, and the placement of line wraps).

How 'bout starting my making the window as high as you can, then call
(posn-at-point (point-max)), then shrink the window accordingly?
