I think it's awesome you can past in SVG. I can't seem to find out how to do it.
If you import a file from the animations editor via choosing the "Open" button, then pick an SVG, you can set the raster size and import it as a bitmap.
Ashley Why do we need to raster the SVG file? Why not make the SVG raster itself according to the screen size? It would make it way more viable.
BTW, can you please answer my question? https://www.scirra.com/forum/how-do-i-use-the-official-steam-plugin_t192463

There's no good way to automatically decide the SVG raster size, so it's up to you. Using an automatic size would either degrade the quality in some cases, or waste memory in others.
