The current Pango version is 1.48.0, but in order to buid Gtk4, a precompiled binary, 'pango-view' must be run. This binary is compiled against Pango 1.50.6, which is the version currently available in Ubuntu 22.04, and uses an exported function, 'pango_glyph_string_index_to_x_full()', that was added precisely in Pango 1.50 (https://docs.gtk.org/Pango/struct.GlyphString.html).
This patch updates Pango version to 1.50.6 to fix this.
