Found a difference of behavior between Cairo Quartz in 1.9.8 and 1.12.x versions of Cairo (which resulted in a bug in our application). Some guidance would be appreciated. We create surface with "surface_for_cg_context" where cg context is that of a view on iPhone screen. For "retina" displays, with cairo 1.9.8 surface is created sized in "points" with 2.0 scale transform (which is our desired behavior - to match the view of non-retina devices). With cairo 1.12 surface is created without the transform (i.e. sized in "retina" pixels). In our case that results in scaled down image covering top left quarter of the view. What is the reason for this discrepancy? What should be the correct behavior and how do we handle it?
