With Reuben and Matt’s help, I cleaned up the official Direct2D Feature Overview to account for changes since initial release.
I clarified that workarounds (like avoiding get/setPixelAt, needing to scope the Graphics context when manually setting pixels, avoiding setBufferedToImage) are no longer needed.
I also added an “Improvements since initial release” section at the bottom and will continue to maintain that.
Outside of those resolved issues/workarounds and the “Golden Rules” in the feature overview, I’m not aware of any more tips needed to upgrade — but I’m happy to add any if people have them.
There are some remaining improvements to the renderer being discussed in this thread.
