Add strings for new errors, documentation fix.

Rewrite for clarity and efficiency.
Use a temporary pixmap to avoid possible BadMatch when fetch from windows.

Don't try to use RENDER to composite glyphs in the absence of the RENDER extension.
Use _cairo_pattern_get_surface instead of _cairo_pattern_get_image.

Add missing cairo_surface_destroy and tidy up offset calculations as suggested by Owen.
Simplify code for computing the extents of clipping area, by introducing a couple of cairo_rectangle_t functions.
The patch removes the create_surface function pointer from the surface vtable and moves much of that code into a couple of helper functions. The composite, compsite_trapezoids, and show_glyphs backend functions are updated to take a cairo_pattern_t instead of a surface as the source.
Change these functions to not create a surface for the pattern and just pass the pattern down to the backend functions.
New function to translate a set of trapezoids.

src/cairo.h src/cairo_ft_font.c: Make cairo_ft_font_create() and cairo_ft_font_create_for_ft_face() take a font scale; make the latter take load_flags for FT_Load_Glyph() as well. Change cairo_ft_font_face() to Xft-style cairo_ft_font_lock_face, cairo_ft_font_unlock_face.
Remove the name/slant/weight=>unscaled font cache, it didn't work with the new cairo_font_t setup. If it turns out to be needed, it can be added back in some other form.
src/cairoint.h src/cairo_font.c: Add a 'flags' field to cairo_glyph_cache_key_t, we use it for load flags with freetype backend.
Switch the caching to be from resolved fontconfig pattern => file; keep only a fixed number of FT_Face objects open at once, similar to FreeType.
src/cairo_gstate.c src/cairoint.h: Add public cairo_font_glyph_extents, use it to implement _cairo_gstate_glyph_extents().

Fix encoding.
Insert new includes for backend-specific header files.
Remove redundant include of cairo-features.h.
Rename header-exclusion macro from _CAIRO_H_ to CAIRO_H. Remove platform-specific grubbing for cairo-features.h and pixman.h in odd places.
Remove all backend-specific prototypes, (as they are now in their own header files).
Remove deprecated
Remove printf.
Convert to utf-8. Use the proper name for multiple-header exclusion (CAIRO_FEATURES_H). Track rename of FREETYPE_FONT_FEATURE to FT_FONT_FEATURE.
Split cairo.h up into cairo.h, cairo-ft.h, cairo-glitz.h, cairo-pdf.h, cairo-png.h, cairo-ps.h, cairo-xcb.h, cairo-xlib.h. Update for rename of cairo_wideint.h to cairo-wideint.h.
Rename CAIRO_HAS_FREETYPE_FONT to CAIRO_HAS_FT_FONT, (to match cairo_ft_font functions and cairo-ft.h).
Update for public header files now in /cairo.
Change type of 'surface' argument in show_glyphs to void * as it is for all other surface virtual functions.
Update accordingly.
Add check for endianess.
Fix bug in array growing loop. (_cairo_array_append): Accept NULL for elements argument, in which case we just allocate space in the array.
Remove cache memory usage assertions as single objects can be larger than the cache size
Decompose font matrix transformations into a couple of helper routines. Return all metrics in font space.
Eliminate compiler warning
Expect glyph metrics to be in font space. Compute text extents by fetching one glyph metric at a time, transforming to user space and computing the overall bounding box.
use 'sincos' where available. Scale factors now ensure the non-scale transform is area preserving. Scale factors requires another parameter to mark the fixed axis.
Change license to LGPL Mark int32x32_64_mul as broken (which it still is)
Ensure each glyph is located as close to the specified position as possible
interface change to _cairo_matrix_compute_scale_factors
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.
