[cairo] Should libgdiplus work with cairo-0.4? config looks for 0.3 only.

[Jeff Kowalczyk]

I am emerging gentoo mono packages, and a keyword dependency,
libgdiplus-1.1.5, fails to configure if it does not find cairo-0.3. I have
cairo-0.4 installed.

Before I file a bug with the libgdiplus maintainers, is it accurate to
characterize cairo-0.4.x as a '0.3-compatible cleanup' release while the
API was reworked for cairo-1.0? Should applications like libgdiplus and
SVG-enabled mozilla build as well with cairo-0.4 as they do with cairo-0.3?

Thanks.
