gpuicn v0.9.3

gpuicn v0.9.3

A request from Matty: embed cards can hold a click-to-load placeholder where
their image goes, for applications that ask before loading remote images.
The change is additive; the runtime pins are unchanged: GPUI Kit 0.9.0 on
gpui-pre 0.3.11 and gpui-icons 0.6.0.

Added

• Embed: ImagePlaceholder, passed to LinkPreview::image_placeholder,
  MessageEmbed::image_placeholder or MessageEmbed::thumbnail_placeholder
  in place of the image (#111).
  • It takes the box the image would take, so nothing moves when the image
    loads: the card's inner width at the pixel size from .size(w, h), or
    16:9 when the size is unknown, large below the text or a thumbnail on the
    right by the same rules as image.
  • A muted surface shows the image icon, "Load image" and the host, and
    fills with the accent color on hover.
  • It is a button named "Load image from {host}" with the focus ring. Click,
    Enter or Space runs on_load once; fetch the image there and pass it
    through image on the next render. label and aria_label replace the
    text, such as for a translation.
