Release 1.12.8 (2012-11-24 Chris Wilson <chris at chris-wilson.co.uk>)
===================================================================
Another couple of weeks and a few more bugs have been found and fixed,
it is time to push the next point release. Many thanks to everyone who
reported their issues and helped us track down the bugs and helped
testing the fixes.
Bug fixes
---------
Expand the sanity checking for broken combinations of XSendEvent and
ShmCompletionEvent.
Notice that "The X.Org Foundation" sometimes also identifies itself
as "The Xorg Foundation".
Handle various ages of libXext and its Shm headers.
Fix the invalid clipping of the source drawable when using SHM
transport to upload images.
https://bugs.freedesktop.org/show_bug.cgi?id=56547
Handle all Type1 postscript operators for better font compatibility.
https://bugs.freedesktop.org/show_bug.cgi?id=56265
Fix a couple of memory leaks in Type1 font subsetting
https://bugs.freedesktop.org/show_bug.cgi?id=56566
Tighten the evaluation of the start/stop pen vertices, and catch a few
instances where we would use a fan instead of a bevel.
https://bugs.freedesktop.org/show_bug.cgi?id=56432
Fix assumption that geometric clipping always succeeds with the
span-compositor.
https://bugs.freedesktop.org/show_bug.cgi?id=56574
Fix call to spline intersection when evaluating whether a stoke is
visible.
Remember to copy inferior sources when using SHM to readback the
surface for use as a source.
Complete list of changes since 1.12.6
-------------------------------------
Adrian Johnson (5):
type1-subset: parse all operators
type1-subset: restore correct callothersub behavior
type1-subset: ensure subroutine numnber is an integer
type1-subset: fix memory leak
type1-subset: remove unused variable
Chris Wilson (19):
version: Post release bump to 1.12.7
xlib/shm: Sanity check that the server handles XSendEvent with ShmCompletion
xlib: Check for both X.org and Xorg ServerVendors
xlib/shm: Check for XShm headers
xlib/shm: Use shmstr.h instead of shmproto.h if available
xlib: Apply the image offsets to the destination rather the source
pen: First check whether the in/out edges lie within the single pen vertex
xlib/shm: Fix bogus assertion without shm available
image: Add a couple of tracepoints for spans fallbacks
stroke: Precompute the line half-width
util/show-polygon: Show the limited range of each edge
spans: Do not assume that we manage to perform the clip geometrically
xlib: Fixup standalone header compilation for 'make check'
gl: Tune the default VBO size to reduce overhead on embedded devices
pen: Tighten checking for bevel (start==stop) joins
test: Add stroke-clipped
stroke: Fix calling '_cairo_spline_intersect' for in-bounds checking of splines
xlib/shm: Need IncludeInferiors when creating the source fallback
1.12.8 release
Kevin Tardif (1):
type1-subset, cff-subset: Plugged 2 memory leaks
What is cairo
=============
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System (via both Xlib and XCB), quartz, win32, and image buffers,
as well as PDF, PostScript, and SVG file output. Experimental backends
include OpenGL, BeOS, OS/2, and DirectFB.
Cairo is designed to produce consistent output on all output media
while taking advantage of display hardware acceleration when available
(for example, through the X Render Extension).
The cairo API provides operations similar to the drawing operators of
PostScript and PDF. Operations in cairo include stroking and filling
cubic Bézier splines, transforming and compositing translucent images,
and antialiased text rendering. All drawing operations can be
transformed by any affine transformation (scale, rotation, shear,
etc.).
Cairo has been designed to let you draw anything you want in a modern
2D graphical user interface. At the same time, the cairo API has been
designed to be as fun and easy to learn as possible. If you're not
having fun while programming with cairo, then we have failed
somewhere---let us know and we'll try to fix it next time around.
Cairo is free software and is available to be redistributed and/or
modified under the terms of either the GNU Lesser General Public
License (LGPL) version 2.1 or the Mozilla Public License (MPL) version
1.1.
