e5d48545e0 Rename __internal_linkage to cairo_private and move it to the beginning of the line for function declarations. Also, drop unneeded "extern" from function declarations. 2004-12-21 13:22:44 +00:00

1a21b8289f With thanks to Kristian Høgsberg <krh@bitplanet.net>: 
Tag a few private functions/data that were missing __internal_linkage.
Mark cache backends as static.

eecfec86f1 Re-enabled __internal_linkage for all internal functions. Now avoid the warning by moving the * from the return type after the __internal_linkage macro. It looks awaful, but it keeps the compiler quiet. 2004-12-20 09:53:06 +00:00

5c1c5e67dc Add _cairo_gstate_restore_external_state, _cairo_fixed_integer_floor and _cairo_fixed_integer_ceil. 
Call _cairo_gstate_restore_external_state on restore.
Fix cache-misses.
Implement floor and ceil
Restore surface clip region on restroe.
(_calculate_region_for_intermediate_clip_surface), (_cairo_gstate_clip_and_composite_trapezoids), (_cairo_gstate_show_surface), (_cairo_gstate_show_glyphs): Create intermediate clip surfaces of the minimal required size.

e3fe2138fe Split off from _cairo_xlib_surface_create to avoid roundtrip when size is already known. (cairo_xlib_surface_create): Simplified to just call XGetGeometry that defer to _cairo_xlib_surface_create_with_size. Add comment about remaining roundtrip and possible plans to eliminate it later with a new interface requiring width/height. 2004-12-20 08:52:47 +00:00

725d363877 Change return value from cairo_status_t to cairo_int_status_t to match definition in cairo_surface_backend_t. 2004-12-20 07:38:38 +00:00

31534f264c Add bug about gcc 3.4 warning: '__visibility__' attribute ignored on non-class types. 
Remove __internal_linkage macro from all functions returning pointers to shut up warning from gcc 3.4.

5c143241df Note that text_cache_crash is expected to fail. 
Add test to demonstrate bug when item is too big for cache.
Really remove that refcount assertion this time.
 2004-11-23 13:38:09 +00:00

7478ea5051 Add note that bug has been fixed. (main): Instrumentation code for testing cache destruction. 
Support tests that produce no output, (don't check image if (width,height) == (0,0)).
Add #include <assert.h> here rather than in multiple .c files.
Add const qualifier to static cache_arrangements table. (_cache_sane_state): Remove refcount assertion as it it false during the cairo_cache_destroy. (_cache_sane_state): #include <assert.h> moved up to cairoint.h (_entry_destroy): Fix bug in assertion (used_memory >= entry->memory), not >. (_cairo_cache_destroy): Fix timing of refcount decrement so that the destroy function actually works.

2b76ec2d46 Unconditionally destroy the old font, (otherwise, if the same font was selected twice in a row, a reference was lost to it, leading to assertion failures). 2004-11-13 19:46:18 +00:00

ed08ea6bba Change the signs of a variety of metrics, which were backwards. 
Return early if we found a rectangular clip at all, not just in error case.
Give render glyphset entry the negative bbox offsets it wants, not the bearings.

f8e632ab1e Add initial regression test suite. 
Don't AC_SUBST a dozen different FOO_CFLAGS and FOO_LIBS. Instead, incrementally build up just CAIRO_CFLAGS and CAIRO_LIBS.
Don't list flags that should get picked up via dependency information through Requires.
Add description of move_to_show_surface.
