Is including higher-resolution icons in the base Anki package a possibility for users with pixelation issues?

Hello!

I have a user who commented that the `icons/speaker.png` icon I use on dialog windows in AwesomeTTS looks very pixelated on OS X, particularly with a retina display. As a test, I tried grabbing the vector versions of the icons that Anki took from the Oxygen icon set and re-rendering them at 256x256.

Even on my Linux desktop with a normal display, the difference in the Xfce task switcher is pretty dramatic:

My question: if an add-on author wants to use such icons on top-level windows, should they bundle a high-resolution version of the icon themselves, or is this something that would be better managed in the base Anki package?

I honestly do not know how many other add-on authors leverage the base package's icons, but if it's more than a few major add-ons, then maybe it makes sense for us to be mostly pulling from the same baseline pool of icons. ~~From my testing, it looks like Qt will scale images down appropriately for wherever they are being used~~ With some exceptions that need fixing (like the yellow popup notices), images are scaled into place, so I *think* that the images can just be swapped out, but maybe putting them in with different filenames would be safer. Additionally, once I ran these images through `optipng`, their file sizes weren't *too* large compared to the lower-resolution images they replaced.

If there is any interest in working on the icons in the base package, let me know what I can do to help. Otherwise, I think I should just be able to bundle the icon in the add-on.

Thanks!
