Summary: switching between verses takes long esp. wi Unicode mods

Initial Comment:
I have BT 1.5.3 on KDE 3.5.1 from Debian unstable.

Here I talk about using the arrow buttons from the 
bible diaply window to switch to the next / previous 
verse.

The time to do this improved in from BT 1.5.1 to 
1.5.3 I think. It is usable meanwhile if you have 
only ISO 8859-1 modules in your display window. I had 
four bibles in parallel with a ~40 verse chapter and 
it took approx 1 sec which is acceptable.

However exchanging one of these four by a Greek 
module using the Gentium font made the "verse change 
time" increase to 2 secs. That's too long to use it 
for setting a temporary bookmark while reading.

Perhaps the "verse change time" can be improved if 
you use JavaScript to do the highlighting of the 
current verse rather than rendering the same content 
anew? But I don't know if khtml supports JavaScript 
in your setting.

It seems that display rendering time improved in the meantime. Expect it
to be better for 1.7.
We will also think about implementing JavaScript for the text handling
later, after we switched to QTWebkit. Thank you for the suggestion.

I don't like JavaScript. It will make debugging very hard. We should stick
with html/xml.
