Pull Request Desription

Please check if the PR fulfills these requirements

• [x] The commit message follows our guidelines
• [ ] Tests for the changes have been added (for bug fixes / features)
• [ ] Docs have been added / updated (for bug fixes / features)

Be aware that the PR request cannot be accepted if it doesn't pass the Continuous Integration tests.

• What kind of change does this PR introduce?

  • [x] bug fix
  • [ ] feature
  • [ ] docs update
  • [ ] other:

• What is the current behavior? (You can also link to an open issue here)

see #1039

• What is the new behavior (if this is a feature change)?

  Takes into account device pixel ratio on any system so that OpenGL rendering and picking works with device (physical) coordinates. tested on :

  • [x] macos
  • [x] linux
  • [x] windows

Event management not related to openGL rendering still remains based on Qt logical coordinates.

• Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?)

• Other information:

Gizmo manipulation computations remain in logical coordinate, even if the openGL part of the Gizmos relies on physical coordinates.

The "scale" of the display (and then the devicePixelRatio) could be changed dynamically, without restarting the app. If two displays with different dpi are used, moving the app from one display to the other also get the right devicePixelRatio.

I'll propose a fix soon.
