[Interest] Crazy idea of the day: QML Image source inception

[Gunnar Sletta]

To some extent this this is already possible. Why does it have to be an Image specifically, though? 

You can cache an item subtree using Item::layer.enabled = true, or by loading the said .qml with a Loader and turn that into a texture (which is what an image actually is) using ShaderEffectSource.

cheers,
Gunnar

Sometimes I want this to be a typical image (PNG, JPG, SVG) but occasionally I'd like to be able to use a QML.  I realize I can do some generation and write an image provider and jump through all those hoops, but something like this should be built in? It may also be possible to do some createComponent wizardry, and use two elements. But it remains that
