Subject: stylecontext: Add _gtk_style_context_peek_property()
X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=2c8ef919ae79bdb676b0250911534d5896e77009;p=~andy%2Fgtk

stylecontext: Add _gtk_style_context_peek_property()

This allows peeking at the computed value for a property. This is useful
for looking at GtkCssImage.
