(sfnt_step_edge_by): Step edge by previously computed step_x.
(sfnt_build_outline_edges): Adjust for already closed contours.
Ignore edges abandoned after grid fit. Also precompute step_x
to avoid multiplication on each span rastered.
(sfnt_poly_edges): Improve alignment.
(sfnt_fill_span): Rewrite to avoid control flow in while loop.
(sfnt_poly_span): Remove unnecessary code.
(sfnt_raster_glyph_outline): Use raster stride instead of width.
(sfnt_test_edge, sfnt_test_raster, main): Improve debugging
code.
* src/sfnt.h (struct sfnt_glyph_outline): Add refcount field to
outline.
(struct sfnt_build_glyph_outline_context): Remove private
struct.
(struct sfnt_raster): Add refcount field to raster.
(struct sfnt_edge): Improve doc. Add `source_x' field used when
built with TEST.
(SFNT_CEIL_FIXED): New macro.
* src/sfntfont-android.c (sfntfont_android_saturate32)
(sfntfont_android_scale32, sfntfont_android_mul8x2)
(sfntfont_android_blend, U255TO256)
(sfntfont_android_composite_bitmap, sfntfont_android_union_boxes)
(sfntfont_android_put_glyphs, sfntfont_android_get_cache): New
functions.
(android_sfntfont_driver): New font driver.
(Fandroid_enumerate_fonts): New function.
(syms_of_sfntfont_android_for_pdumper, init_sfntfont_android)
(syms_of_sfntfont_android): Initialize default fonts, special
family mapping and font driver.
* src/sfntfont.c (struct sfnt_font_desc): New fields
`char_cache', `cmap_invalid' and `subtable'.
(sfnt_setup_coding_system): Improve commentary. Add default
branch. Fix return value.
(sfnt_safe_encode_coding_object_1)
(sfnt_safe_encode_coding_object_2):
(sfnt_safe_encode_coding_object): Use decode_coding_object
instead of encode_coding_object.
(sfnt_decode_font_string): Adjust for rename.
(sfnt_decode_foundry_name): New function.
(sfnt_weight_descriptions, sfnt_slant_descriptions)
(sfnt_width_descriptions): Fix definitions.
(sfnt_parse_style): Make function work.
(sfnt_enum_font): Initialize designer, char-cache and subtable
platform ID.
(sfntfont_charset_for_name, mark_sfntfont)
(sfntfont_charset_for_cmap): New functions.
(syms_of_sfntfont): New variable `sfnt-default-family-alist'.
* src/sfntfont.h (_SFNTFONT_H_): Update prototypes.
* src/xdisp.c (gui_union_rectangles): New function.
