* src/Makefile.am:
Add cairo-lzw.c to sources
Remove erronous space at start of line
* src/cairo-lzw.c:
New file implementing _cairo_compress_lzw which does Lempel-Ziv & Welch
compression as used by postscript. Based on code from libtiff.
* src/cairo-output-stream.c:
Add _cairo_output_stream_write_base85_string which implements
an encoder for the ASCII85Decode postscript filter.
* src/cairoint.h:
Add _cairo_compress_lzw and _cairo_output_stream_write_base85_string.
* src/cairo-ps-surface.c:
Write Images LZW + Base85 encoded.
Change ps level to 2 (we only needed level 3 for FlateDecode).
Change DocumentData to Clean7Bit as we don't include binary data
anymore.
Surely, the ! instead of ~ here was just a typo. I'd feel better if I
had a failing test case for this though, (time to break out gcov
again).
Fixes bug #6185:
Strange pointer operations in fbCompositeTrans_0888xnx0888 (pixman/src/fbpict.c)
https://bugs.freedesktop.org/show_bug.cgi?id=6185
Bogus fix; misunderstood the relationship between the font bearings
and the computed device offsets. Real fix on my device offsets branch.
This reverts 49b4fe10d0 commit.
cairo-ft-font was being naughty and storing glyph bearings in the
surface device_[xy]_offset fields -- this had no effect previously,
because _cairo_surface_composite ignored those fields, but once it
starts handling device offsets itself, this causes ft text rendering
to break.
All test targets now list an expected cairo_surface_type_t. Add notes
on current limitations of PDF/PS/meta-surface support that causes
CAIRO_CONTENT_COLOR similar surfaces of PDF and PS surfaces to be
returned as image surfaces.
Add cairo_internal_surface_type_t for the meta, paginated, and various
test surfaces.
If the BitBlt in get_image fails, we pretty much can't do anything -- so
fill the destination with white and hope for the best. This enables
somewhat accurate printing of complex operations. Also, check the
destination device caps before calling AlphaBlend; return UNSUPPORTED if
the destination DC can't do AlphaBlend.

If the DC is a display DC, inspect its depth and set out local format
appropriately. If it's not a display DC, assume RGB24.
