Subject: src/svgtiny_css.c: define a css_select_handler
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;ds=sidebyside;h=b90df4ac34f3873c235392568f6b35ec8d56e78f;p=libsvgtiny.git

src/svgtiny_css.c: define a css_select_handler

We define a css_select_handler structure full of all of the select
handlers we've just implemented. This is the big piece of the puzzle
that we need before we can call css_select_style().
