Haiku (OS) caches the vector icons rendered from HVIF[1][2] files which are used extensively for UI.

I didn't find details of the caching design. Possibly it was mentioned to me by waddlesplash on IRC[3].

> The drawback to using vector images is that it can take longer to render a vector image than a bitmap; you basically need to turn the vector image into a bitmap at the size you want to display on the screen.

Indeed, would be nice if one of these blogs explained the caching solution to tackle the drawback.

Another issue, I think, especially at smaller sizes, is the pixel snapping might be imperfect and require "hints" like in fonts? Wonder if these icons suffer from these/address it
