+Subject: [PATCH] librsvg.pc.in: add libcroco to Requires.private
+
+libcroco is a mandatory dependency since version 2.35.0 so add it to
+Requires.Private to fix a static build failure with imagemagick
+
+This patch is not upstreamable as librsvg no longer depends on libcroco
+since version 2.47.1. It now does all CSS processing using Rust crates
+from Mozilla Servo.
