[PATCH weston 2/2] simple-egl: Only set alpha_size=0 when -o is passed.

[Scott Moreau]

When starting simple-egl with -f for fullscreen and toggling to 'windowed' mode with F11,
the surface is opaque instead of semi-trnasparent as it is when starting without -f. We
only want to create the surface with alpha_size=0 when the user explicitly passes -o
because otherwise it will never have the ability to use alpha.
