are fixed, also a heap write overflow in SVG/Rendering and various other
bugs. Notable behaviour change:
* JPEG: The JPEG reader now allows 3 warnings of any particular type
before giving up on reading and throwing an exception. This choice
was made after observing files which produce hundreds of warnings
and consume massive amounts of memory before reading the image data
has even started. It is currently unknown how many files which were
previously accepted will be rejected by default. The number of
allowed warnings may be adjusted using '-define
jpeg:max-warnings=<value>'. The default limit will be adjusted
based on reported user experiences and may be adjusted prior to
compilation via the MaxWarningCount definition in coders/jpeg.c.
