[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] Linux Squeak VM X11 keyboard changes breaks 32b VM (#396)

[kksubbu]

Thank you, Nicolas, for your detailed analysis of the code path for handling keystrokes in the editor. Initially, I too traced this path and noticed that EventSensor>>processEvent: maps keystrokes using KeyDecodeTable before calling processKeyboardEvent. Key alt-d correctly invoked cmdActions in both 32b and 64b images but ctrl-d invoked shiftCmdActions in 32b image instead of cmdActions. The KeyDecodeTable is different in these two images.

I agree that the sqUnixX11.c file is very messy and confusing. It mixes X11 terms (raw keycode and mapped keysym) with Squeak specific terms (keycode, charcode).  JB's patch broke 32b image but not 64b. I proposed a partial rollback of this patch to get TimJ going while we sort out the mess.
