Changeset 2055 for libcaca/trunk/cacaTweet

Timestamp:

Nov 25, 2007, 3:11:58 PM (13 years ago)

Author:

Sam Hocevar

Message:

• Add cucul_manage_canvas() and cucul_unmanage_canvas(). Display drivers no longer need to access the cv->refcount private member and cucul_set_canvas_size() is no longer needed.
