[Twitch] Support Stream - Unreal Motion Graphics (UMG) UI - Oct. 21, 2014

Could you explain what was meant by the following quote from the UE 4.5 Release notes?

DPI Scaling

Unreal Motion Graphics now supports automatic scaling for resolution-independent UI. We now provide default DPI scaling rules for all games. You can configure this in your project’s Rendering settings.

Is this related to the the following card (Trello) in the roadmap?

Mac Editor Retina support
This involves a lot of reworking assumptions in Slate.

As far as I understand, there is no support for vectors/SVGs so I don’t quite get how the button graphic is resolution-independent.
Since the text comes from fonts which contain vectory glyphs, I could see how that could be resolution-independent. However, you could also just be scaling down the text textures there too, depends how it is implemented behind the scenes.

Edit: Found this nugget from Michael Noland, text does seem to be resolution-independent.

Slate actually handles something like this with a runtime atlas for font characters, rasterizing characters as needed at each scale size used in a frame. This works pretty well in practice, though quickly zooming in and out in a Blueprint can pollute the cache temporarily.

For those users (gabrielefx, RPotter and anyone else) interested in vector support, please post a reply to this post Unreal Engine Vector Graphics Support so we can show Epic how many people are interested in this.
