In AdvanceFrame(), timeout refers to the timeout of the *next* frame. Setting
the *current* animation frame time based on the *next* frame is nonsense, but
worked for images with uniform frame timings. Unfortunately some images
don't have uniform frame timings!
Prior to this change, isBrowserContentDocumentDisplayed returned false
from the time that the isFirstPaint flag was set in layout to the time
that layout handed off the rendered document to the compositor. However
the way the function is used meant that it needs to return false until
the compositor actually composites the "first-paint" rendering,
otherwise other events can sneak in and run before the compositor. This
patch moves the tracking for the flag into GeckoLayerClient so that it
can be queried and modified synchronously from both the Gecko thread in
browser.js and the compositor thread in setFirstPaintViewport.
When 'font-family' is secified with unquoted identifiers rather than a quoted string, a single space should be inserted between identifier tokens, even if they are separated by a comment rather than a whitespace token.
The code in nsHTMLStyleSheet implements LangRule to map xml:lang into
style and the code to manage its uniqueness.
The change to nsGenericHTMLElement fixes the mapping of the HTML lang
attribute to do cascading the way all other rule mapping does so that
the cascading works correctly.
The tests test that the correct style language is used for hyphenation
by copying over a set of hyphenation reftests that check its basic
response to languages. There are no specific tests for font selection,
but font selection is known to use the same language data from style.
I verified manually (see other attachments to bug) that the rule
uniqueness is being managed correctly.
