The FT_LOAD_TARGET_* flags aren't separate bitfields, but rather an embedded subfield, so test with FT_LOAD_TARGET_MODE (val->key.flags) == FT_RENDER_LCD, and similar.

src/cairo-font.c src/cairo.h src/cairoint.h: Add a cairo_font_options_t object to cairo_scaled_font_create().
src/cairo-surface.c src/cairoint.h: Add virtualized cairo_surface_get_font_options() to get the font options for a surface.
Adapt to cairo_scaled_font_create() change.
Add an implementation of get_font_options() that turns off metrics hinting.

Add valgrind suppressions for libpng/libz use of uninitialized data. There are clearly bugs here that are not cairo's fault as zeroing the buffer before writing the png image actually causes more errors(\!). And, notably, setting all the data to random bytes usually makes the errors go away.
...
Change the check-valgrind target to include the .valgrind-suppresions file and to tee output into valgrind.log.

(_cairo_hash_table_insert): Document that it is now a fatal error to insert an entry with a key that matches an existing entry.
(_cairo_hash_table_random_entry): Add predicate function so that the user can select a random entry satisying the given predicate.
(_cairo_hash_table_remove): Change return type to void since failure is really not possible here.
