30eea3915b resources: Regenerate image golden testdata
Keep this as a separate commit as this isn't because the files have changed. The filenames have changed due to cache busting of PNG and Webp images.

0a2ab3f8fe exif: Allow more spacing characters in strings
The root cause of issue #8079 was a non-breaking space (U+0160).
`unicode.IsPrint` only allows the ASCII space (U+0020).  Be more lenient
by using `unicode.IsGraphic` instead.

Fixes #8079

3ba147e702 images: Add images.Overlay filter
This allows for constructs ala:

```
{{ $overlay := $img.Filter (images.Overlay $logo 50 50 )}}
```
Or:

```
{{ $logoFilter := (images.Overlay $logo 50 50 ) }}
{{ $overlay := $img | images.Filter $logoFilter }}
```

Which will overlay the logo in the top left corner (x=50, y=50) of `$img`.

With this you can do variants of this:

```
{{ $img := resources.Get "images/misc/3-jenny.jpg" }}
{{ $img := $img.Resize "300x" }}
{{ $g1 := $img.Filter images.Grayscale }}
{{ $g2 := $img | images.Filter (images.Saturate 30) (images.GaussianBlur 3) }}
```
