Hello Roman,

Cool! This change makes scrolling in JTextArea fast enough for actual usage,
even in interpreted mode (jamvm).

Nitpicks:

Unfortunately, mouse-clicks don't seem to position the text cursor correctly,
and double-clicking doesn't select a word/line/paragraph but some randomly
selected word/line/paragraph. IIRC, this used to "work" two weeks ago (if
one waited long enough...).  Should I report this as a new bug?

Mouse-wheel scrolling still only scrolls down... btw, your recent scrolling
change seems to have broken this for JTree, too :-) But this should be easy
to fix now.
