Subject: Remove magic LaTeX::TikZ::Interface->import
X-Git-Tag: v0.01~15
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FLaTeX-TikZ.git;a=commitdiff_plain;h=af7d6a5aef3bf5fec0c187b3a13a14adc88251fd

Remove magic LaTeX::TikZ::Interface->import

One should use ->register now. It has been made into a class method.
