Fix FFI prototypes for cairo_scaled_font functions
These functions had parameters incorrectly marked as ptr-to-mutable
while the C declarations have these parameters as ptr-to-immutable.

cairo_scaled_font_text_extents takes a *const c_char not a *mut c_char.
cairo_scaled_font_glyph_extents takes a *const Glyph not a *mut Glyph.
cairo_scaled_font_text_to_glyphs takes *const c_char not *mut c_char.

Implement missing ScaledFont functions
This adds the following new functions:


This function has a large unsafe block due to
cairo_scaled_font_text_to_glyphs returning two pointers that are
allocated using opaque methods, i.e. not under our control, and so must
be copied into Vec<>'s.

The other option would have been to return a special container type for
[Glyph] and [TextCluster] that called the relevant
cairo_{glyph,text_cluster}_free function upon drop. Less copying but
greater complexity and poor ergonomics.


I opted for an explicit allocation and return of a FontOptions structure
(wrapped opaque pointer) instead of allowing a caller to pass in an &mut
FontOptions as I felt that wasn't idiomatic Rust code.

Move major font types to its own modules

Make glib dependency optional
The cairo bindings used the glib::translate traits to handle internal
reference counting discipline. However, these are not actually
required, and should be possible to use cairo without a dependency on
glib. This patch makes the dependency optional, and changes the
implementation to not use the glib traits internally.
