Chromium treat AltRight key as "AltGraph" modifier if the keyboard layout
has AltGr key.
When AltRight key is pressed with a keyboard layout which has AltGr key,
modifiers should as following:
1. "keydown" for ControlLeft:
ctrlKey: true, altKey: false, getModifierState("AltGraph"): false
2. "keydown" for AltRight:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
3. Some "keydown", "keypress" and "keyup" events:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
4. "keyup" for ControlLeft:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
5. "keyup" for AltRight:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): false
So, only when the preceding "keydown" event for ControlLeft, ctrlKey should
be set to true as usual. However, after AltRight key is pressed actually,
we should treat "AltGraph" modifier is true and both ctrlKey and altKey
should be set to false for web apps can handle text input normally.
So, MODIFIER_ALTGRAPH and MODIFIER_CONTROL/MODIFIER_ALT should not be set
at the same time.
This patch makes ModifierKeyState have only MODIFIER_ALTGRAPH or
MODIFIER_CONTROL/MODIFIER_ALT.
Additionally, this patch makes VirtualKey::ShiftState treat "AltGraph" as a
modifier. So, now, VirtualKey needs to convert ShiftState to index value when
it accesses its mShiftStates array. Therefore, this patch adds
VirtualKey::ToIndex() and make each VirtualKey method use it before
accessing mShiftStates.
Note that this patch also fixes bug of WinUtils::SetupKeyModifiersSequence().
The constructor of KeyPair takes 2 keycode values, but the second virtual
keycode can have scancode to distinguish if the key is left or right.
However, WinUtils::SetupKeyModifiersSequence() never sets scancode to
KeyPair. Therefore, it fails to dispatch AltRight key event.

Mostly just convert nsInt{Rect,Region} to LayoutDeviceInt{Rect,Region}.
One exception is to change the parameter of nsWindow::OnResize from
nsIntRect to LayoutDeviceIntSize, because it really only needs that.

Bug 1354020 causes that IMM-IME on Windows 7 doesn't work with --no-remote. Although I think that this issue is OS or IME bug, when default window proceduce by RegisterClass is DefaultWindowProcW, Google Japanese IME doesn't work.
I am not sure why this issue occurs when lpfnWndProc is DefWidnowProcW and DDE isn't started. But for workaround, we should revert a part of bug 1354020 changes.

When removing our Windows message loop pumping code in the content
process, a11y code on the MTA thread must have some way to wake up the
main thread. The main thread could be blocked either on a conditional
variable waiting for a Gecko event, or it could be blocked waiting on
a Windows HANDLE in IPC code (doing a sync message send). In the
former case, we wake it up by posting an event to the main thread. In
the latter case, we continue to use the asynchronous procedure call
mechanism.

Since committing will do IO on the main thread, it would be better to do it on
an idle thread instead. We have to change JavaScript code too because now the
API is asynchrous.
This patch also updates its xpcshell test.
Now mozilla::widget::AsyncDeleteAllFaviconsFromDisk will get profile directory
on the main thread to prevent it happens on off-main-threads, thus prevents
off-main-thread assertion.

The sandbox blocks loading of GMPs when the GMP resides in a directory stored
in a path which contains a symlink or junction point. So resolve GMP paths
fully before instantiating the GMP process.

In TSF mode, application should retrieve messages with ITfMessagePump::GetMessage() or ITfMessagePump::PeekMessage() since TSF/TIP may handle the message before or after the host application handles it.
This patch rewrites the API users with WinUtils::(Get|Peek)Message() which use ITfMessagePump if it's available.

This patch started life as making ImageEncoder.cpp:EncodingRunnable not
use nsAutoArrayPtr, but the API effects rippled out from there. On the
whole, I think using UniquePtr throughout has made the code clearer.
