Certainly, we definetively should :^)

I talked to Jim Gettys about the magnifier and he proposed to utilize
X Composite Extension to provide a better support and performance (but
then only on computers that support it). Is that more or less what you
are planning?

What is cursor tracking?

I do have a on-going scientific research about the usability of the
magnifier. The answers show that the users are very satisfied. Most
feature requests are about the dynamic mode (to be implemented with X
Composite Extension on the near future).

Since 3.2.1 it´s very good I would say.

It works as a fullscreen software that enlarges a portion of the
screen that is inside a glass.

But an image is probably worth much more then many words, so here is a
screenshot of it:

Object pascal, like Delphi. Althought the official compiler is Free
Pascal you do can use Delphi to compile it. Interfacing between pascal
and c or c++ is very easy and natural. You can even mix c / c++ object
files with pascal ones to link and executable.

The widgetset interface links to gtk 2 on unixes.

Well, not yet =) We didn´t think about that before, but this can
probably be easely implemented, either throught a library or an
mechanism to control the executable.

What exactly do you need? I am not familiar with orca, thought I will test it.

thanks,
