I'm confused on both points.
1. How is cairo_format_from_content well-defined?
There's already not a one-to-one correspondence between formats and
content, (does CONTENT_ALPHA map to FORMAT_A8 or FORMAT_A1 ?), and
this will only get worse as we add more format types.
It was exactly for the reason that we expected to add more formats
in the future that we decided to separate the notions of content
2. Given "they are not the most useful functions for user programs",
what's the point of discussing this? Let's talk again when a user
has a need that can't be met with the current API, OK?
