Draft: [Debian 11] Apply patch from 3.24.35 to fix Wayland + EGL on GLES-only platforms
Previously, GTK assumed that EGL could use the OpenGL API everywhere, but some proprietary drivers like those for Raspberry Pi and Vivante only support OpenGL ES. Allow use of OpenGL ES to be forced via environment variable GDK_GL=gles.
Closes: #1020937
