bspwm: Add HiDPI support for GTK applications

Browse Source 
It turns out that GDK_SCALE and GDK_DPI_SCALE is what you need to add
HiDPI support to GTK applications. Since you probably have .Xresources
adjusted for your HiDPI display, you will need to set both GDK_SCALE and
GDK_DPI_SCALE at the same time to render things properly.

Ironically, I never got this to work before. Maybe because I was always
using 'GTK_SCALE' instead of 'GDK_SCALE', or maybe because I never used
both GDK_SCALE and GDK_DPI_SCALE at the same time.

This gives me full HiDPI support in bspwm, with the exception of a few
applications (polybar, dunst) that don't honor DPI as of this writing.
