[gui] [PATCH] Fixes to TextComponent and TextArea

[David Jee]

Hi,

I committed the following patch to the java-gui-branch.  It fixes a
couple bugs related to TextComponent and TextArea.  First, it makes sure
that the text cursor is set to the beginning of the text, to match Sun
AWT's behaviour.

It also eliminates an infinite feedback loop problem, where a call to
TextArea.repaint() will cause a GTK expose event, which results in a
call to TextArea.repaint() again.  A mechanism to stop this type of
problem was already in place; TextArea just needed to be handled
separately.
