#PangoCairo bindings for MoonBit

Native MoonBit bindings for the core PangoCairo layout and rendering functions. The package composes the existing tonyfettes/pango and tonyfettes/cairo bindings without exposing either package's C wrapper layout.

The bindings cover context resolution, context/layout creation and updates, layout and glyph rendering, path construction, error underlines, and the Cairo font-map interface. Font options, scaled fonts, the Cairo-font interface, and shape-renderer callbacks are intentionally deferred.

Context, font : &@tonyfettes/pango.IFont
IFont, glyphs : @tonyfettes/pango.GlyphString
GlyphString, start : Int, end : Int) -> Bool

Adds glyphs in the half-open range [start, end) to cr's current path.

The glyph positions are relative to Cairo's current point, matching glyph_string_path. An empty range is a successful no-op. Returns false without changing the current path when the range is outside glyphs. A true result means the range was submitted; inspect cr.status() for Cairo drawing errors.
