Subject: Remove the user_constraint feature from the autocoercion code
X-Git-Tag: rt87282~2
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FLaTeX-TikZ.git;a=commitdiff_plain;h=7ba67fb7132be201995057c8102d5df578dac20c

Remove the user_constraint feature from the autocoercion code

We don't need it and it makes the code harder to look at than necessary.
