8669b870af image: Fix textures and bg color not reloading 
The reload procedure for changed image files is triggered
but the old data has to be deleted to be re-generated.

e710419a22 decoder: Add basic color profile support 
This only covers 8bit RGB(A) JPEG, PNG, and HEIF.
Should only be a temporary solution until GTK supports
color profiles.

Closes #36

e8aa5451c3 decoder: Avoid unwraps and report issues to UI 
Those are mostly cases that should never occur.
But especially for rare erros it can be helpful to
directly display them in the UI.

fad8bb7939 decoder: Use GFile instead of PathBuf 
This allows to show images from locations that don't
have a representation with path.

This also works around not being able to read files in trash:///

Closes #56

f8cc9f5f84 i18n: Use gettext function instead of wrapper 
No need to deviate from the default here.

ca672552be decoder: Bring back support for still WebP images 
We manually have to use the static decoder instead of
the frames api as for PNG.

65e967c235 decoder: Detect HEIC/HEIF via guessed mime type 
This will not cover files with wrong extensions. But
we don't have a magic byte sniffer in place yet.

7bf9baa581 image: Ensure contrast for transparent images 
Determine if the image is transparent and has low
contrast with default background color. If so,
use a different background color.

e5fc4bc85c image: Add high DPI support 
Always interpret the scaling percentag in physical pixels.
This makes 100% show the image 1:1 in screen pixels.

67207bb215 image: Use mipmaps for zoom-out and NN for zoom-in 
Before we always used "linear" filtering. This gave
a harsh image with moire patterns when zooming out
and washed out images when zooming in.

Closes #68, #71

42d558d22f propertiesView: Use image dimensions from decoder 
This also shows the units for SVG dimensions if not pixels.

a2a9b4134b propertiesView: Use decoder format 
Use the format that we actually used when decoding.
The mime type is usually derived from the file extension
which might not always be correct.

See <https://gitlab.gnome.org/GNOME/librsvg/-/issues/938>

5217d39cd3 tiling: Revert using append_scaled_texture 
It slows down zoom and pan and has no use yet.

f80ec7db56 decoder: Use image-rs, libheif-rs, librsvg 
This adds proper support for a lot of image formats including SVGs.
It will be the basis for many features to come. The technical core
is an asynchronous renderer that can arrange textures in smaller tiles
which might be generated on demand.

Closes #34, #40, #41, #49

Basis for fixing the following issues #7, #27, #36, #43, #68, #71
