Yes, good idea.

You'd compare the code with my version. There are a few tweaks that are 
needed for Cuis. Oh, and there are many CR characters in there...

I did
    FFITestPoint2 defineFields.
    FFITestPoint4 defineFields.
And all test pass. :) Maybe they'd be called from a class side 
#initialize method?

StyledTextEditor Extended Clipboard. Allows copying / pasting not only 
text, but Forms (bmp/png/tiff), RTF, all this between Cuis and other 
apps, and even complete morphs or other complex objects if between 2 
Cuis images. There is an ExtendedClipboardPlugin for Mac, with full 
functionality. For Windows, there is a limited functionality (can paste, 
but can not copy into Windows clipboard) done using FFI.
