From: Carl Worth <email@example.com> Date: 6 Dec 2006 To: firstname.lastname@example.org CC: email@example.com Subject: cairo snapshot 1.3.6 available A new cairo snapshot 1.3.6 is now available from: http://cairographics.org/snapshots/cairo-1.3.6.tar.gz which can be verified with: http://cairographics.org/snapshots/cairo-1.3.6.tar.gz.sha1 c69339afca1115815be50b32c3a733d272aaa84c cairo-1.3.6.tar.gz http://cairographics.org/snapshots/cairo-1.3.6.tar.gz.sha1.asc (signed by Carl Worth) Additionally, a git clone of the source tree: git clone git://git.cairographics.org/git/cairo will include a signed 1.3.6 tag which points to a commit named: 648ef4487dfa43f20fb2c73e7b8e567f8a25497a which can be verified with: git verify-tag 1.3.6 and can be checked out with a command such as: git checkout -b build 1.3.6 This is the third development snapshot in the 1.3 series. It comes two weeks after the 1.3.4 snapshot. We don't have fancy performance charts this week as the primary changes in this snapshot are bug fixes. The performance work continues and the next snapshot (planned for one week from today) should include several improvements. -Carl Summary of changes since 1.3.4 ============================== * Fix undesirable rounding in glyph positioning (Dan Amelang) This bug was noticed by several users, most commonly by seeing improper text spacing or scrambled glyphs as drawn by nautilus. For example: Update to cairo-1.3.4 worsen font rendering https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=217819 * Fix reduced range of valid input coordinates to tessellator (M Joonas Pihlaja) This bug was causing lots of assertion failures in mozilla as mentioned here: CAIRO_BO_GUARD_BITS and coordinate space? http://lists.freedesktop.org/archives/cairo/2006-December/008743.html * Fix several regressions in new tessellator (M Joonas Pihlaja) Joonas just had a good eye for detail here. I don't think any external cairo users had noticed any of these bugs yet. * Fix compilation problems of cairo "wideint" code on some platforms (Mathieu Lacage) * Fix failed configure due to broken grep (Dan Amelang) This bug was reported here: AX_C_FLOAT_WORDS_BIGENDIAN doesn't work because grep doesn't work with binary file https://bugs.freedesktop.org/show_bug.cgi?id=9124 * Remove the pkg-config minimum version requirement (Behdad Esfahbod) Some systems ship with pkg-config 0.15 and there was really no good reason for cairo to insist on having version 0.19 before it would build. There is also one new (but inert) feature in this snapshot. There's a new option that can be passed to cairo's configure script: --disable-some-floating-point Disable certain code paths that rely heavily on double precision floating-point calculation. This option can improve performance on systems without a double precision floating-point unit, but might degrade performance on those that do. As of this snapshot, this option does not make any change to cairo, but it is possible that future versions of cairo will respect this option and change the implementation of various functions as appropriate.
