Re: draw using pycairo on glut interface

Dear Prashant,

I don't have experience with Cairo, but either if it's a software or
GPU-based renderer, there might be a way to capture its output and use it
as a texture.

If Cairo is software based, check to see if you can have it render to a
byte array or color matrix, then (after proper formatting) use that to
create a 2D texture.

If Cairo is GPU-based, and it uses OpenGL, you should be able to have it
render to a FBO (with a texture color attachment) or Pbuffer.

Once you have a texture, you can map it on a quad or a triangle fan aligned
to the screen. Results will be better if you use an Orthographic projection.

I hope these ideas help. If anyone knows about Cairo, please do weight in :)

Best,
Alejandro.-
