Changes since the last tag '2.42.3':

Dmitry Kontsevoy (4):
      yield the identity transform for empty transform attribute
      aspect_ratio.rs: split AlignMode into (x,y)
      aspect_ratio.rs: use cssparser
      aspect_ratio.rs: move (x,y) parsing to AlignXY

Federico Mena Quintero (112):
      gitlab#214 - Pass cargo flags to "cargo test"
      Merge branch 'librsvg-2.42' into 'librsvg-2.42'
      Depend on float-cmp so we can get traits for approximate comparisons for floats
      New trait FixedEqCairo with a fixed_eq_cairo() method
      New trait ApproxEqCairo
      path_builder.rs: Use approx_eq_cairo() instead of direct float comparisons
      pattern.rs: Tighten division-by-zero guards; use approx_eq_cairo()
      util.rs: Make DBL_EPSILON private; we'll remove it soon
      RsvgBbox: use approx_eq_cairo() instead of double_equals()
      marker.rs: Use approx_eq_cairo() and float_cmp::ApproxEq instead of double_equals()
      structure.rs: Use approx_eq_cairo() instead of double_equals()
      viewport.rs: Use approx_eq_cairo() instead of double_equals()
      util.rs: Remove DBL_EPSILON and double_equals().  Yay!
      Use ApproxEq again in ApproxEqCairo.  This lets us compare big numbers, too.
      CONTRIBUTING.md: Link to ARCHITECTURE.md
      ARCHITECTURE.md: Document how to compare floating-point numbers
      CI: Do all the distros at the same time
      Remove unexported/unused rsvg_cairo_to_pixbuf()
      Aaaaargh, remove parse_transform.lalrpop - it's been unused for ages
      gitlab#227 - Catch negative values in stroke-dasharray
      gradient.rs: Release acquired nodes if they are not of the type we expect
      NodeUse: release the acquired node as soon as possible; to refactor later
      AcquiredNode: new wrapper over acquire_node()/release_node()
      gradient.rs: Use AcquiredNode
      marker.rs: Don't pass an extra c_node; we can get it from the node
      marker.rs: use AcquiredNode
      paint_server.rs: Use AcquiredNode
      structure.rs: Use AcquiredNode
      pattern.rs: Use AcquiredNode
      drawing_ctx.rs: Removed unused acquire_node()/acquire_node_of_type()/release_node()
      pattern.rs: Remove the FallbackSource stack
      pattern.rs: Handle patterns with no children in a cleaner way
      Prettify the rather horrible while() loop in resolve_pattern()
      gradient.rs: Remove FallbackSource; use acquired nodes instead
      gradient.rs: Refactor the resolution loop similarly to pattern.rs
      AspectRatio.is_slice: new method, so image.rs can avoid peeking into the struct's innards
      AspectRatio: make everything but the toplevel struct private
      aspect_ratio.rs: Return AttributeError from the helper parsers
      aspect_ratio.rs: Simplify parse_align()
