[go-nuts] [ANN] Cairo bindings

Hello,

I'd like to announce Golang bindings for the Cairo graphics library:
   https://godoc.org/github.com/martine/gocairo/cairo

There are other projects which aim to do the same thing [1], [2], [3].
  However, all are incomplete -- compare the lengths of the relevant godoc
links -- and some appear abandoned.

I aimed to make this one complete and regular by taking an alternative
approach: I parse the C header to gather all the functions and types and
then generate the wrapper (in an idiomatic Go style) from there.

Caveats:
- I've written some example programs
at https://github.com/martine/gocairo/tree/master/example but I haven't
verified all the API works as expected.
- This implementation is still missing some of the advanced Cairo functions
such as text glyph/cluster management, raster sources, and some of the file
I/O functions.
- There are a few more transformations of some of the API I'd like to do to
better match Go style; I have some gathered in the TODO list at
https://github.com/martine/gocairo/blob/master/notes.org . More
suggestions are welcome. For an example bikeshed, which is better:
  AddColorStopRGBA(offset float64, r, g, b a float64)
  AddColorStopRGBA(offset, r, g, b a float64)
?
