(144/231) 3487005 - Char rendering errors

I tested the newest version 21121 from trunk
with scripts of the world. See my enclosed test document.

Though I cannot read most of these languages,
it looked fine to me :-) but I found a rendering error
for ancient Egypt hieroglyphs (chars above BMP);
there is a straying rectangle, which does not belong there.

Perhaps the tokens in do not always start with the correct
surrogate for chars above BMP?

the defect rectangle is the 3rd character from the last position;
the browsers IE, Firefox and the unicode text editor "babelpad"
show everything correctly

I found one issue more;
the very first combined character in "Tengwar" is not rendered correctly;
the horizontal bar must be centered and not at the bottom.
I attach screenshot.

The malayalam issue is only in jedit compiled Win7+ Java7, not in Ubuntu11+Java6. The other bugs remain.
Malayalam is basic unicode plane, Tengwar is basic plane: Private Use Area, Ancient egypt is secondary plane.
