[Spice-devel] [PATCH 0.8 1/2] client: handle the redundant right ctrl windows' message send when a alt-gr is pressed bz#709074

[Gal Hammer]

Hello,

I first updated the translate_key function. It now requires the windows 
message as parameter (will be used later). It also use the raw wparam 
and lparam parameters in order to remove the code duplication when 
calling the function.

    Gal.
