Re: [pygame] subsurfaces outside of their parents

[Forest Darling <fdarling@xxxxxxxxx>]

No, it needs to appear to be 20x20 because the whole idea is to have
whether or not its off the surface to be transparent. This makes it so
code can draw 0, 0, --> 20, 20 on the subsurface without having to
compensate for being off the surface and such... I want this feature,
personally, for a widget drawing system involving subsurfaces.
