[cairo] applying alpha to a pattern

[Theo Veenker]

Hi,

Given a path that I need to stroke/fill with an arbitary pattern (solid color,
gradient or suface based), is it possible to stroke/fill it with alpha applied
to the pattern?  I guess I'm basically looking for cairo_{stroke|fill}_with_alpha()
or a procedure to achieve this efficiently.

Would it make sense to add something like cairo_{stroke|fill}_with_alpha() or
perhaps to add an alpha attribute to cairo_pattern_t? It would make fading
in/out graphics a lot easier I think.
