Support images and other formats for icons

[ddkwork]

hello you, In addition to SVG, APP and Button, Chosenr and other controls support setting ICO, PNG and other icon formats? If not, is there a way to convert ICO and PNG to SVG?

I will look into this soon.

I made a tool for embedding image files into svg files, which you can use to accomplish using images for icons. To install it, run:

go install cogentcore.org/core/svg/cmd/svg@main

Example usage:

svg embed-image my-image.png

This will put create a file called my-image.svg that has the image embedded into it. Then, you can use that SVG file as an icon by adding the svg file to the icons filesystem. I will work on improving the way you extend the icons filesystem soon, but currently you can look at https://github.com/goki/kid/blob/main/buttons.go for an example. The most important lines in that example are:

//go:embed icons/*.svg
var providerIcons embed.FS

func init() {
	icons.Icons = merged_fs.NewMergedFS(icons.Icons, grr.Log1(fs.Sub(providerIcons, "icons")))
}

I improved the structure for extending the icons library, so you can just do this:

//go:embed icons/*.svg
var myIcons embed.FS

func main() {
    icons.AddFS(grr.Log1(fs.Sub(myIcons, "icons")))
    // the rest of your code
}

And you can put all of your icons in an icons directory in your code using the svg embed-image command I showed in the last comment.

And you can reference your icons using their string filenames without the extension. For example:

gi.NewButton(b).SetIcon("my_icon_name")

gi.NewButton(b).SetIcon("my_icon_name")

I Will try, thanks.
