window-list: Allow smaller panel heights

[soreau]

Set the scrolled window policy to NEVER instead of AUTOMATIC to allow it to become smaller than 32 pixels in height.

trying to build from window-list-height branch and getting errors. not sure why it says "wayfire found no". and i have glm installed.

Found pkg-config: YES (/usr/bin/pkg-config) 2.1.0
Found CMake: /usr/bin/cmake (3.28.2)
Run-time dependency wayfire found: NO (tried cmake)

meson.build:16:17: ERROR: Dependency lookup for wayfire with method 'pkgconfig' failed: Could not generate cflags for wayfire:
Package glm was not found in the pkg-config search path.
Perhaps you should add the directory containing `glm.pc'
to the PKG_CONFIG_PATH environment variable
Package 'glm', required by 'wf-config', not found
