Subject: src/svgtiny_internal.h: add CSS context to parser state
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=a01e70298e4aa9239b2494b1c2129e0fc952295b;p=libsvgtiny.git

src/svgtiny_internal.h: add CSS context to parser state

Add a css_select_ctx pointer to the svgtiny_parse_state that is
threaded through each phase of SVG parsing. This will allow us to
populate the context with any <style> sheets we find; later, we can
consult those stylesheets while constructing our svgtiny_diagram (the
abstract representation into which we parse an SVG).
