GTK misbehaves at scale factors >2

Submitted by Drew DeVault

I have issues running GTK software on Wayland compositors with a scale factor of 3 or greater. I observe two problems:

gnome-terminal has weird shadows:

gedit crashes when I hover over buttons on the title bar:

Gdk:ERROR:gdkdisplay-wayland.c:1109:_gdk_wayland_display_get_scaled_cursor_theme: assertion failed: (scale <= GDK_WAYLAND_MAX_THEME_SCALE)

If a high enough resolution cursor is not available, GTK should fallback to a lower resolution and let the compositor upscale it.
