[cairo-announce] cairo snapshot 0.5.2 now available

[Carl Worth]

A new cairo snapshot 0.5.2 is now available from:

        http://cairographics.org/snapshots/cairo-0.5.2.tar.gz
        http://cairographics.org/snapshots/cairo-0.5.2.tar.gz.md5
        56073c9c7bb1f7acbd278d298aa42b5f  cairo-0.5.2.tar.gz

This doesn't have a lot of big changes. We do hope to have a bigger
cairo 0.6.0 within the week.

Snapshot 0.5.2 (2005-07-18 Carl Worth <cworth at cworth.org>)
==========================================================
API changes
-----------
* New functions for creating patterns of a single color:

	cairo_pattern_create_rgb
	cairo_pattern_create_rgba

* Change cairo_surface_create_similar to accept a new type of
  cairo_content_t rather than cairo_format_t:

	typedef enum _cairo_content {
	    CAIRO_CONTENT_COLOR		= 0x1000,
	    CAIRO_CONTENT_ALPHA		= 0x2000,
	    CAIRO_CONTENT_COLOR_ALPHA	= 0x3000
	} cairo_content_t;

* Add new CAIRO_FORMAT_VALID and CAIRO_CONTENT_VALID macros.

* Remove unused status value:

	CAIRO_STATUS_NO_TARGET_SURFACE

* Add new status values:

	CAIRO_STATUS_INVALID_STATUS

* Require libpixman >= 0.1.5 (for necessary bug fixes)

Bug fixes
---------
* Fix cairo_surface_write_to_png for RGB24 images.

* Fix broken metrics and rendering for bitmap fonts. Add mostly
  useless bitmap glyph transformation.

* Fix glyph caches to not eject entries that might be immediately
  needed, (fixing intermittent crashes when rendering text).

* Fix all memory leaks found by running "make check-valigrind".

ATSUI backend changes
---------------------
* Allow building against < 10.3 SDK.

* Prevent crash on empty strings.

Glitz backend changes
---------------------
* Require glitz >= 0.4.4.

* Use frame buffer objects instead of pbuffers for accelerated
  offscreen drawing.

* Minor improvement to gradient pattern creation.

PostScript backend fixes
------------------------
* Rewrite of the PS backend to generate more interesting output that
  the old big-image implementation.

Win32 backend fixes
-------------------
* Implement glyph path support.

* Fix swap of blue and green values in the fill_rectangles path.

Xlib backend fixes
------------------
* Add optimization to use XCopyArea rather than XRenderComposite when
  transforming only with an integer translation, and using SOURCE
  operator or OVER with a source pattern without alpha.
