Nothing in GTK+ appears to be suited for what are virtually infinite lists. Our workaround with GtkLabel and GtkScrolledWindow is heavily suboptimal and needs to be replaced.

Use Pango directly to handle our relatively simple needs. Replicate the behaviour of sdtui when in doubt.

gdk_pango_layout_get_clip_region() can be used to retrieve clip regions for text selection. Other functions exist to retrieve what position corresponds to display coordinates. pango_cairo_layout_path() can be used to override the foreground colour (Pango markup may specify colours of its own, even if it's not currently supported; besides, I believe pango_cairo_show_layout() will employ some optimisations).

It is more than possible to just import colours from sdtui configuration.
