However, it seems like almost the whole stack trace could be avoided
if this call cached its results somehow:
org.apache.fop.fonts.Font.getCharWidth(Font.java:231)
(an array of 65536 elements would be enough, but wouldn't be terribly
efficient in terms of memory.)
So the solution may lie in between: make the call once per *used*
character.
It's highly unlikely that a document will contain all 64K characters
anyway...
Whereas that's true (I wasn't planning to call it for all 64k characters
anyway, just as necessary) I was thinking of minimising the lookup time
by looking the character up in an array vs. using a HashMap. But I
guess the initial version can use a HashMap and I'll see what happens
from there. I guess calculating the hash will be trivial at least. :-)
