Re: Canvas shortcomings

[Lauris Kaplinski <lauris ximian com>]

Hello!

Unreachable goal IMHO :(
I have not yet find a way to make a graphic API, that:
1) has reasonable speed and quality
2) can be used for both interactive and output graphics
3) has single, consistent API

If anybody knows the solution, I would be very interested.

Best wishes,
Lauris Kaplinski
