Hello everyone,
While working on something involving transparency, I noticed that the
=E2=80=98alpha-background=E2=80=99 frame parameter can also be given as a f=
loat (see
=E2=80=98gui_set_alpha_background=E2=80=99 in src/frame.c). This patch upda=
tes the
documentation to note this fact.

Hello everyone,
While working on something involving transparency, I noticed that the
=E2=80=98alpha-background=E2=80=99 frame parameter can also be given as a f=
loat (see
=E2=80=98gui_set_alpha_background=E2=80=99 in src/frame.c). This patch upda=
tes the
documentation to note this fact.

Hello everyone,
While working on something involving transparency, I noticed that the
=E2=80=98alpha-background=E2=80=99 frame parameter can also be given as a f=
loat (see
=E2=80=98gui_set_alpha_background=E2=80=99 in src/frame.c). This patch upda=
tes the
documentation to note this fact.
