Add API to query whether a modifier is consumed Currently the user has no way of knowing which of the active modifiers have been used in the translation of a keycode to its keysyms. The use case is described in the GTK docs: say there's a menu accelerator activated by "<Alt>+". Some layouts have "+" shifted, and some have it on the first level. So in keymaps where "+" is shifted, the Shift modifier is consumed and must be ignored when the user is testing for "<Alt>+". Otherwise, we may get "<Alt><Shift>+" and the accelerator should not actually fire. For this we also use the preserve[] information in the key types, which can forces us to report modifiers as unconsumed even if they were used in the translation. Until now we didn't do anything with this information. The API tries to match its surronding. It's not very efficient but this can be fixed. Signed-off-by: Ran Benita <ran234@gmail.com>
