We're wanting to show the Matomo logo/icon in the app like this:

The mobile version would basically look like this:

Here's the high res circle image with transparent background:

Problems:

• I don't think we have the icon as an SVG but are showing the logo as an SVG in all places.
• If we decide to show an image instead, we would need to combine above circle and the word "Matomo" into one image. But likely it be blurry in various places.

Ideally we create an SVG version of the logo.
