the same benefit as one which has simply been idle for a while. Use

ephyr: don't allow a shift+ctrl keygrab if mod1 was enabled

Xephyr wants ctrl+shift to grab the window, but that conflicts with
ctrl+alt+shift key combos. Remember the modifier state on key presses and
releases, if mod1 is pressed, we need ctrl, shift and mod1 released
before we allow a shift-ctrl grab activation.

Xi: Ensure DeviceChanged is emitted after grabs are deactivated

When a grab on a slave device is deactivated, the master device must
be checked, just in case there were events from other devices while
the slave device was stolen away by the passive grab. This may
introduce misbehaviors on mismatching valuators and device features
later on UpdateDeviceState().

xfree86: Use the TMDS maximum frequency to prune modes

Instead of only relying on the Range section, we can do better on
