Add new path query functions.
Implement support for cairo_current_path and cairo_current_path_flat. These functions just provide an interface to _cairo_path_interpret and take care of mapping from device space back to user space.
cairo_path.last_move_point and cairo_path.current_point are now fixed-point not doubles for consistency.
Now accept 4 explicit function pointers rather than a structure. Eliminate unnecessary done_path callback.
Track change in _cairo_path_interpret. Code previously in done_path callback is now here immediately after call to _cairo_path_interpret.
Internal _cairo_path API modified to accept fixed-point data everywhere. Much cleaner this way.
Have to convert doubles to fixed-point to track changes in _cairo_path API.
Keep data in fixed-point rather than going through intermediate doubles. Track changes in _cairo_path API.
New function to help when working with freetype.
New function. (cairo_surface_set_filter): Store filter in surface.
Declare.
Copy filter setting. (_cairo_xlib_surface_set_filter): Use constants from Xrender.h
Remove all 'extern ' and ' __external_linkage' (macro for __declspec(dllexport) and __declspec(dllimport)) from function declarations. These are no longer needed for cygwin.
Changed type of _line_segs_intersect_ceil from 'static cairo_fixed_t' to 'static int' to match definition. This was necessary to compile under cygwin.
Add current_point state. (_cairo_path_current_point): New function. (_cairo_path_rel_move_to): (_cairo_path_rel_line_to): (_cairo_path_rel_curve_to): New functions.
Eliminate current_point state. (_cairo_gstate_show_text): (_cairo_gstate_text_path): Use new _cairo_path_current_point.
Compute x,y now needed by cairo_font_text_path. (_cairo_gstate_glyph_path): Track change in cairo_font_text/glyph_path (path argument is now last).
Switch to new macro-based mechanism for including freetype headers. (cairo_ft_font_face): (cairo_ft_font_pattern): Minor cleanup. (_cairo_ft_font_copy): (_cairo_ft_font_destroy): (_utf8_to_glyphs): (_cairo_ft_font_font_extents): (_cairo_ft_font_glyph_extents): (_cairo_ft_font_text_extents): (_cairo_ft_font_show_glyphs): (_cairo_ft_font_show_text): Track changes to cairo_font_backend_t interface.
Track changes to cairo_font_backend_t interface.
Clean up implementation. (_cairo_ft_font_glyph_extents): Initial implementation. Thanks to John Ellson <ellson@research.att.com> for most of the work on this function. (_cairo_ft_font_show_text): Clean to use num_glyphs not nglyphs.
Re-enable cairo_text/glyph_extents.
_utf8_to_glyphs now accepts a point by which each glyph should be offset. (cairo_ft_font_backend): Remove evil void * casts on function pointers.
Fix to not require a current point.
Move initialization of current device-space point from setup_text_rendering_context to _cairo_gstate_show_text. (_cairo_gstate_show_glyphs): Fix to not reference current point.
Get rid of AC_PATH_XTRA. Instead, find X includes/libraries only via pkg-config xrender. Switch option from --without-x to --disable-xlib Add option --disable-ps
Add -lz only if ps_surface backend is compiled.
Rename functions and indentifiers with ic_ in the name that were missed by the recent renaming. Fix indentation problems left by the recent renaming.
Shift everything over from libic/libpixregion/slim to libpixman. Many thanks to Dave Beckett <dave.beckett@bristol.ac.uk> for all of the heavy lifting with this renaming effort.
Switch from libic to libpixman.
Include pixman.h not ic.h. (__external_linkage): Directly fold in slim stuff rather than depending on it from an external package.
Look for libpixman instead of libic and slim.
New support for "./configure --without-x" to compile without the xlib backend. Many thanks to Sasha V. <sasha@aftercode.net>.
We do three things here: Make the pkg-config check for xrender conditional, set XLIB_BACKEND_DEFINE to either CAIRO_HAS_XLIB_BACKEND or CAIRO_HAS_NO_XLIB_BACKEND to be substituted into cairo-config.h, and set an AM_CONDITIONAL for HAVE_XLIB_BACKEND to enable conditional compilation of cairo_xlib_surface.c. Perhaps that could be simplified a tad, but it's what we have working now. Also split up various PKG_CHECK_MODULES into separate checks.
Remove errant reference to cairo_gstate_set_drawable.
Move xlib-specific calls in from old cairo-xlib.h, now guarded in #ifdef CAIRO_HAS_XLIB_BACKEND.
Make compilation of cairo_xlib_surface.c conditional. (INCLUDES, libcairo_la_LIBADD): Add the new variables from splitting up the PKG_CHECK_MODULES calls.
Use cairo_point_double_t not XPointDouble, (to avoid false dependency on X headers). Thanks to "Sasha V." <sasha@aftercode.net> for pointing these out.
Do nothing if the pen is a degenerate, single point. This happens when the line width is a very small, non-zero value.
Do nothing when asked to stroke a path with a line_width of 0.0. Previously, this would lead to an infinite loop.
Force negative line width to 0.0.
Updated TODO list.
Added new cairo_in_stroke and cairo_in_fill.
* src/cairo_gstate.c (_cairo_gstate_in_stroke): (_cairo_gstate_in_fill): New functions to support for cairo_in_stroke and cairo_in_fill. Many thanks to Thomas Hunger <info@teh-web.de> for the initial implementation which demonstrated how easy this would be and pushed me to go and write it already.
Fixed to use _cairo_fixed_from_double instead of XDoubleToFixed.
