Changeset 2821 for libcaca/trunk/caca/figfont.cTweet

Timestamp:

Sep 27, 2008, 3:12:46 PM (11 years ago)

Author:

Sam Hocevar

Message:

Starting refactoring to get rid of libcucul. The initial reason for the
split is rendered moot by the plugin system: when enabled, binaries do
not link directly with libX11 or libGL. I hope this is a step towards
more consisteny and clarity.

File:

• libcaca/trunk/caca/figfont.c (copied) (copied from libcaca/trunk/cucul/figfont.c) (30 diffs)
