Includes squashed bugfixes/regressions:
- m-c 1444537: Shutting down the decode pool should make animated decoders bail early
- m-c 1628606: Make sure to mark the surface cache entry available before sending the frame complete notification
- m-c 1502275: Skip recreating the decoder after redecode errors if an animated image is reset
- m-c 1443232: Don't insert frames into our AnimationFrameBuffer that we consider in error and unusable
Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
In the original Windows clipboard BMP decoder implementation in
nsImageFromClipboard::ConvertColorBitMap, if the bitmap used bitfields
compression, it always adjusted the offset to the RGB data by 12 bytes.
It did this even for newer BMP header formats which explicitly include
space for the bitfields in their header sizes. This patch updates our
BMP decoder to do the same for clipboard BMPs, since we have observed
pasted BMPs using bitfield compression appearing incorrectly. To the
user this appears as if we read a color mask; completely red, blue,
green pixels at the start of the last row, causing all of the other rows
to start with the last three pixels of the previous row.
