+Release 1.2.2 (2006-08-08 Carl Worth <cworth at cworth.org>)
+This is the first bug fix release in the 1.2 series since the original
+1.2.0 release made six weeks ago.
+There were some very serious bugs in the 1.2.0 release, (see below),
+so everybody is encouraged to upgrade from 1.2.0 to 1.2.2. The 1.2.2
+release maintains source and binary compatibility with 1.2.0 and does
+not make any API additions.
+Fix crashes with BGR X servers
+With cairo 1.2.0 many people reported problems with all cairo-using
+programs, (including all GTK+ programs with GTK+ >= 2.8) immediately
+crashing with a complaint about an unsupported image format. This bug
+affected X servers that do not provide the Render extension and that
+provide a visual with BGR rather than RGB channel order.

+Fix the "disappearing text" bug
+With cairo 1.2.0 many people reported that text would disappear from
+applications, sometimes reappearing with mouse motion or
+selection. The text would disappear after the first space in a string
+of text. This bug was caused by an underlying bug in (very common) X
+servers, and only affected text rendered without antialiasing, (either
+a bitmap font or a vector font with antialiasing disabled). The bug
+was also exacerbated by a KDE migration bug that caused antialiasing
+to be disabled more than desired.

+Fix broken image fallback scaling (aka. "broken printing")
+The various "print" backends, (pdf, ps, and svg), sometimes fallback
+to using image-based rendering for some operations. In cairo 1.2.0
+these image fallbacks were scaled improperly. Applications using cairo
+can influence the resolution of the image fallbacks with
+cairo_surface_set_fallback_resolution. With the bug, any calue other
+than 72.0 would lead to incorrect results, (larger values would lead
+to increasingly shrunken output).

+Fix inadvertent semantic change of font matrix translation (Behdad Esfahbod)
+The 1.2.0 release introduced an inadvertent change to how the
+translation components of a font matrix are interpreted. In the 1.0
+series, font matrix translation could be used to offset the glyph
+origin, (though glyph metrics were reported incorrectly in
+1.0). However in 1.2.0, the translation was applied to the advance
+values betwen each glyph. The 1.2.0 behavior is fairly useless in
+practice, and it was not intentional to introduce a semantic
+change. With 1.2.2 we return to the 1.0 semantics, with a much better
+implementation that provides correct glyph metrics.

+Fix create_similar to preserve fallback resolution and font options (Behdad Esfahbod)
+There has been a long-standing issue with cairo_surface_create_similar
+such that font options and other settings from the original
+destination surface would not be preserved to the intermediate
+"similar" surface. This could result in incorrect rendering
+(particulary with respect to text hinting/antialiasing) with
+fallbacks, for example.

+xlib: Fix text performance regression from 1.0 to 1.2.0 (Vladimir Vukicevic)
+Several people noticed that upgrading from cairo 1.0 to cairo 1.2.0
+caused a significant peformance regression when using the xlib
+backend. This performance regression was particularly noticeable when
+doing lots of text rendering and when using a high-latency connection
+to the X server, (such as a remote X server over an ssh
+connection). The slowdown was identified and fixed in 1.2.2.

+PDF: Eliminate dependency on FreeType library dependency (Adrian Johnson)
+The cairo 1.2 series adds a supported pdf backend to cairo. In cairo
+1.2.0 this backend required the freetype library, which was an
+undesirable dependency on systems such as win32, (cairo is designed to
+always prefer the "native" font system). As of cairo 1.2.2 the
+freetype library is not required to use the pdf backend on the win32

+PDF: Fix so that dashing doesn't get stuck on (Kent Worsnop)
+Kent notices that with the PDF backend in cairo 1.2.0 as soon as a
+stroke was performed with dashing, all subsequent strokes would also
+be dashed. There was no way to turn dashing off again.
