gfxPlatform::GetSourceSurfaceForSurface and CreateDrawTargetForSurface
are both static methods that we sometimes use via the pattern
gfxPlatform::GetPlatform()->... This is problematic because this forces
gfxPlatform to be initialized in the process, and in the GPU process, we
don't support this. It should be safe to call these methods without
initializing gfxPlatform, so this patch removes the GetPlatform() call.
GetSourceSurfaceForSurface may end up initializing gfxPlatform anyways,
depending on whether or not a DrawTarget was given. This should not be a
concern for the crashes observed in bug 1435586.

`cmd_align` is always with `nsCommandParams` when it's executed. However,
when somebody checks whether the command is enabled or not, or retrieves the
state, `GetInternalCommand()` is called without `nsCommandParams`. Therefore,
even when `nsCommandParmas` is nullptr for `cmd_align`, `GetInternalCommand()`
shouldn't warn it.
Additionally, internal command supports to set `align` to empty string.
Therefore, `GetInternalCommand()` also needs to support it.
This patch adds `Command::FormatJustify` for the former case and
`Command::FormatJustifyNone` for the latter case.
Note that this does not affect to actual behavior since `AlignCommand`
does not refer the result of `GetInternalCommand()`.

When user moves focus to an editable content in a content process, it posts
IME-focus notification to the main process. Then, when the main process

`PuppetWidget` modifies its IME notification requests, but **not** modifying
cache of IME notification requests in its `TextEventDispatcher`. Therefore,
`IMEContentObserver` keep referring older IME notification requests which are

We previously disabled system dark themes for Firefox chrome and content by gtk-application-prefer-dark-theme settings.
That option is no longer preferred by gnome project and was removed from tweaks tools. Theme makers are encouraged to use
a different name for the dark theme variants, like Adwaita-dark, Yaru-dark and so on. This option also does not
work when the GTK theme is missing the light variant completely.
To address that, this patch implements heuristics based on https://www.w3.org/TR/AERT/#color-contrast
to check if the system GTK theme has good contrast/visibility with default HTML colors
(white background and black text).
If widget.content.gtk-theme-override is empty and the system theme fails the test with gtk-application-prefer-dark-theme set to false, then Adwaita:light theme is used.
This patch was tested with some distro default light themes (Ambiance, Radiance, Yaru - Ubuntu, Arc - KDE, Menta - MATE)

`GetInternalCommand()` is currently used only by `EditorCommand` and it
treats the additional parameter only when given command is `cmd_align`.
However, the value is complicated since `AlignCommand` allows both `CString`
value and `String` value. Therefore, `EditorCommand::DoCommandParams()` may
fail to solve `cmd_align` to a `Command` value without checking both of them.
Therefore, it must make sense that `GetInternalCommand()` take `nsCommandParams`
as optional argument and check it only when given command matches `cmd_align`.
Then, we don't need to waste unnecessary run-time cost.
Note that this bug has been hidden since `AlignCommand` class does not refer
the `Command` value but refers only `nsCommandParams`. However, the previous
patch makes `EditorCommand::GetParamType()` not allow `Command::DoNothing`.
Therefore, we need this follow-up fix now.

which just delegates to `DoCommand()`.
This patch adds some undeclared commands but which are handled by

Profiling shows that we're spending a lot of time on startup inside

over to Java to determine whether hardware accelerated video encoding is
supported.
Looking at the Java stacks in the profile, Android is spending most of our time
creating a list of codecs. It doesn't look like there's a faster way to query
for hardware accelerated video support. So to speed this up we can cache the
value in the user's profile. We also store the OS version, which we can use to
detect when the OS is updated so we can invalidate the cache then.
Presumably an OS update is the only way a device can have its hardware acceleration
support status change.
With this change, the time we take figuring out the HW encode/decode status
goes from ~100ms on a cold run to ~0.01ms on a cache hit on my HD8 tablet.

2. If it's for an empty `<input>` element, it has only bogus node.
3. If it's for a non-empty `<textarea>` element, it has a text node and
`moz-<br>` element. Additionally they are followed by `<scrollbar>` and
`<resizer>` elements.
4. If it's for an empty `<textarea>` element, it has a `moz-<br>` element
followed by `<scrollbar>` and `<resizer>` elements.
Additionally, `TextEditRules::WillInsert()` always removes bogus node if
there is. So, in the case #2, there is no children.
Fortunately, we don't support XUL addons anymore on Firefox. However, in
