Dark HDR test image

SUMMARY
You have a lot of options when it comes to cursor in Krita. However, all of the options:
- either rely on XOR (which is not available on ANGLE: it shows a very, very bright green cursor - and ANGLE is the go-to canvas acceleration option on HDR)
- are white or contains white (which is again super bright on HDR display; even one white pixel can be too bright on 1000 nits monitor agains a nearly black area)
- are a single back pixel... which gets lost in dark areas, especially on HighDPI monitors.



STEPS TO REPRODUCE
1. Create a new HDR image, I used elle-g10, 16bit float.
2. Paint on it with dark colors.
3. Try every pssible cursor - all appear super bright or get lost.

OBSERVED RESULT
Very bright cursor or the cursor easily get lost.


EXPECTED RESULT
Cursor is visible all the time, but isn't that bright.


NOTES
It could be just a grey outline or dark grey-light grey cursor, something like that.

I'm an idiot, you totally can change the color of the outline in the options. Changing to mid grey gets rid of the glowing screen and helps painting dark areas.  I use #4f4f4f now.

Still it would be nice to have at least one option in the size-independent cursor to use while sketching (outline gets easily lost) or if someone don't like outline for any reason.

Also all other cursors like color picker suffer from the same issue. It's a bit less important than painting cursor though.
