Subject: xdot_gradient_fillcolor: remove dead store to 'r1'
X-Git-Tag: 2.50.0~32^2~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2b720b83b2b9bc0338d48372216a81bf7a1f9806;p=graphviz

xdot_gradient_fillcolor: remove dead store to 'r1'

This variable is overwritten on line 648 without having been read in between.
This code appears copy-pasted from `cairo_gradient_fill` without noticing that
this line is unused here.
