The people I am familiar with for example have light allergy. Large bright 
areas on the screen hurts their eyes  (e.g. selected text in the GNOME dark 
background colour scheme).

Some additional, intelligent false colour modes would be needed to invert only 
those parts of the screen with bright colours. But as far as I know, no 
existing screen magnifier that can this. Hopefully Gunnar will be able to 
come up with a solution.

It was one result of our usability test with partially sighted users, but I 
need to mention that the group was very small.

Gunnar's magnifier will include something based on XComposite and AT-SPI, and 
I suggested to make it also useful without the magnification.

We are planning to extend the colour schemes in KDE4 to contain enough colour 
roles for the applications, and to provide them with suitable functions for 
gettign additional colours if they really need them. It would be great if we 
could get a common solution for KDE and GNOME.

KDE can already apply its colour scheme to Gtk applications, but this is 
broken, and I have been unable to find a documentation of the Gtk theme

Using XEvie would still mean interfering with the core pointer. I meant cases 
where the on-screen keyboard does not aim to completely replace both the 
mouse and the keyboard. For example, the user enters text via keyboard, and 
uses a standard mouse, but there are also a few buttons in an on-screen 
keyboard for quickly inserting often-used words, or for typing in words in 
different alphabets, etc.
