Version 1.8.4 of Cairo

Changes: Several minor configuration and build issues were resolved. A random crash caused by _cairo_clip_intersect_mask(), causing all rendering to the context to stop, was fixed. Transforming nearly-degenerate matrices into degenerate matrices is now avoided. A few FreeType font handling bugs were fixed. Various documentation improvements were made.

Changes: Several fixes for failures on Quartz and PDF and build fixes for a couple of backends were made. A check for XRender in the XCB backend was introduced to avoid invalid memory accesses.

Changes: Building with older bash and XRender was fixed. Triggering of a bug in X.org server 6.9 is now avoided. A bug in the computation of user-font glyph bounding boxes of Type3 fonts was fixed. A miscomputation of the size of fallback images was fixed. Cairo is now more tolerant of broken fonts when subsetting Type1 fonts. Several further bugs were fixed.

Changes: It is now possible to build Cairo without any font backend, which is most useful when the application provides custom font rendering through the user-font API. A failsafe fallback font is provided, though. Several compilation speed-ups and optimizations were made. Many bugs were fixed.

Changes: Many improvements were made to Cairo's ability to handle text, including a new "user fonts" feature as well as allowing glyphs to be embedded in PDF output along with their original text (for searching, selection, and copy-and-paste). A major revamp of the build system makes it much easier to build Cairo on various platforms. The performance on remote X servers without the Render extension was improved. The output of cairo-ps and cairo-pdf was made more efficient. Completions were made to the API. Many bugs were fixed.
