Subject: [PATCH] Issue #333: continuing to support librsvg 2.40.x (C
|
|
versions).
|
|
|
|
Commit 9beeefcbe uses too new functions of librsvg. We could just bump
|
|
the minimum required version but there are issues with Rust not being
|
|
available on every platform yet. So instead, let's add some conditional
|
|
code paths, so that it still builds with librsvg 2.40.x (which was the
|
|
last versions fully in C) while we use newer code and no warnings when
|
|
using newer versions.
