> This patch replaces my previous borders-respect-alpha-background frame parameter with an alpha-borders
> frame parameter, which lets users set the alpha of borders to whatever they desire.
> 
> Most of the changes are just changing boolean respect_alpha_background parameters to double alpha
> parameters. respect_alpha_background=true gets replaced with f->alpha_background, and
> respect_alpha_background=false gets replaced with 1.0 (opaque).
> 
> I have tested both the GTK3 and PGTK builds.
> 
> One detail I noticed (prior to this patch) is that on X, internal borders are opaque. However, on PGTK,
> internal borders take on the alpha-background opacity. Is this intentional? If not, I'm happy to fix it.

Thanks.  Po Lu, could you take a look, please?
