This looks very interesting. I have plenty of style comments, but I'd 
like first to understand what you are doing.

Ui files are modified as well, but their change is basically to add ImHints properties to the text inputs. Other modifications in Ui files are automatically made by the editor of QtCreator.

This is the part I am interested in (unsurprisingly, I cannot comment 
much on the IM machinery itself).

Could you explain what happens with the positions in the paragraph when 
the preedit string is added? I'd like to understand the changes that you 
need to do.

Do you plan to allow to move cursor during preediting?
