Rewrite a few error strings so that they more closer match the
documentation. Where they differ, I believe I have chosen the more
informative combination of the two texts.
Ensure that no assumptions are made that a small allocation will succeed
by manually injecting faults when we may be simply allocating from an
embedded memory pool.
The main advantage in manual fault injection is improved code coverage -
from within the test suite most allocations are handled by the embedded
memory pools.
_cairo_win32_tmpfile() uses _open_osfhandle() which is not available
on Windows CE. However, Windows CE doesn't have the permisions problems
that necessitated _cairo_win32_tmpfile() in the first place so we can just
use tmpfile() on Windows CE.
Adds an error code replacing CAIRO_STATUS_NO_MEMORY in one case where it
is not really appropriate. CAIRO_STATUS_INVALID_SIZE is used by several
backends that do not support image sizes beyond 2^15 pixels on each side.

Use the return value to return the result from _cairo_hash_table_lookup()
(as opposed to filling an output parameter on the stack) as this (a)
results in cleaner code (no strict-alias breaking pointer casts), (b)
produces a smaller binary and (c) is measurably faster.
Use the surface user-data array allow to store an arbitrary set of
alternate image representations keyed by an interned string (which
ensures that it has a unique key in the user-visible namespace).
Update the API to mirror that of cairo_surface_set_user_data() [i.e.
return a status indicator] and switch internal users of the mime-data to
the public functions.
Chris rightfully complained that having a boolean function argument is
new in cairo_show_text_glyphs, and indeed avoiding them has been one
of the API design criteria for cairo. Trying to come up with alternatives,
Owen suggested using a flag type which nicely solves the problem AND
future-proofs such a complex API.
Please welcome _flags_t APIs to cairo.h
Quick summary of changes:
- Move list of cairo source files out of src/Makefile.am and into
src/Sources.mk,
- Generate files src/Config.mk and src/Config.mk.win32 that choose
the right set of source files and headers based on configured
backends and features. This drastically simplifies building
using other build systems. The src/Makefile.win32 file needs
to be updated to reflect these changes.
- Add README files to various directories,
- Add toplevel HACKING file.
New public API:
cairo_text_cluster_t
cairo_has_show_text_glyphs()
cairo_show_text_glyphs()
Add accompanying gstate and surface functions, and surface backend methods.
No backends implement them just yet.
It was reported by Liu Yubao that cairo_status_t may be chosen to be
an int8_t by the compiler, in that case cairo_int_status_t values
assigned to cairo_status_t would overflow. Fix this by allocating
the values in int8_t range, and add compile-time sanity checks.
