FrameTimeout wraps a frame timeout value (measured in milliseconds) after

image, animation will never start, because IncrementAnimationConsumers is
ignored. If there is another instance that is animated, that's still OK,
because any imgIContainer method that is affected by animation gets its
aWhichFrame argument set to FRAME_FIRST when it passes through FrozenImage.

SUCCESS or not. The other values are primarily useful for debugging and error
handling.
SUCCESS: We successfully drew a completely decoded frame of the requested
size. Drawing again with FLAG_SYNC_DECODE would not change the result.
SUCCESS_NOT_COMPLETE: The image was drawn successfully and completely, but
it hasn't notified about the sync-decode yet. This can only happen when
layout pokes at the internal image state beforehand via the result of
StartDecodingWithResult. This should probably go away eventually, somehow,
see bug 1471583.
INCOMPLETE: We successfully drew a frame that was partially decoded. (Note
that successfully drawing a partially decoded frame may not actually draw any
pixels!) Drawing again with FLAG_SYNC_DECODE would improve the result.
WRONG_SIZE: We successfully drew a wrongly-sized frame that had to be scaled.
This is only returned if drawing again with FLAG_SYNC_DECODE would improve
the result; if the size requested was larger than the intrinsic size of the
image, for example, we would generally have to scale whether FLAG_SYNC_DECODE
was specified or not, and therefore we would not return WRONG_SIZE.
NOT_READY: We failed to draw because no decoded version of the image was
available. Drawing again with FLAG_SYNC_DECODE would improve the result.
(Though FLAG_SYNC_DECODE will not necessarily work until after the image's
load event!)
TEMPORARY_ERROR: We failed to draw due to a temporary error. Drawing may
succeed at a later time.
BAD_IMAGE: We failed to draw because the image has an error. This is a
permanent condition.
BAD_ARGS: We failed to draw because bad arguments were passed to draw().
NOT_SUPPORTED: The requested operation is not supported, but the image is
otherwise valid.

| imgIContainer.idl |
This represents an image's intrinsic size, in units of pixels (the same
units as our 'width' and 'height' attributes). Both components are
optional, because an image (particularly a vector image) may lack an
intrinsic width and/or height.
We use signed types for the components, but the values are expected to be
nonnegative; any negative values should be considered an error. (Zero is
valid, though.)
Note that this is similar to a gfx::IntSize, except for the use of Maybe<>
to reflect that the components are optional. This is also similar to
nsIFrame.h's mozilla::IntrinsicSize class, with the difference being pixel
units here vs. nscoord units there.

nsIIconURI
This interface derives from nsIURI, to provide additional information

What *is* a moz-icon URI you ask? Well, it has the following syntax:
moz-icon:[<valid-url> | //<file-with-extension> | //stock/<stock-icon>]?
['?'[<parameter-value-pairs>]]
<valid-url> is a valid URL spec.
<file-with-extension> is any filename with an extension, e.g. "dummy.html".
If the file you want an icon for isn't known to exist, you can use this
instead of a URL and just place a dummy file name with the extension or
content type you want.
<stock-icon> is the name of a platform-dependant stock icon.
Legal parameter value pairs are listed below:
Parameter: size
Values: [<integer> | button | toolbar | toolbarsmall | menu |
dialog]
Description: If integer, this is the desired size in square pixels of
the icon
Else, use the OS default for the specified keyword context.
Parameter: state
Values: [normal | disabled]
Description: The state of the icon.
Parameter: contentType
Values: <mime-type>

A SurfacePipe is a pipeline that consists of a series of SurfaceFilters

some way before the SurfaceSink ultimately writes it to the surface. This
design allows for each transformation to be tested independently, for the
transformations to be combined as needed to meet the needs of different
situations, and for all image decoders to share the same code for these
transformations.
Writing to the SurfacePipe is done using lambdas that act as generator
functions. Because the SurfacePipe machinery controls where the writes take
place, a bug in an image decoder cannot cause a buffer overflow of the
underlying surface.
