Added rotated bounding boxes

[bsekachev]

Motivation and context

Resolved #1128

How has this been tested?

Manual testing

TODO:

• Add a couple of jest tests
• Add angle visualization
• Fix migrations
• Add default values in bindings
• Add exporting as polygons (in case of mask), add exporting additional attribute in other cases

Checklist

• I submit my changes into the develop branch
• I have added description of my changes into CHANGELOG file
• I have updated the documentation accordingly
• I have added tests to cover my changes
• I have linked related issues (read github docs)
• I have increased versions of npm packages if it is necessary (cvat-canvas,
  cvat-core, cvat-data and cvat-ui)

License

• I submit my code changes under the same MIT License that covers the project.
  Feel free to contact the maintainers if that's a concern.

@ActiveChooN @zhiltsov-max Could you please review this patch?

@bsekachev , somewhere the precision is lost. Always N.0 is dumped like 72.0 even if in UI I see 71.6

[nmanovic]

@bsekachev , for tracked boxes I see the same problem. All boxes has integer coordinates indeed.

[nmanovic]

@bsekachev , also I tried to set the angle to 'zero'. It is just impossible. Need to redraw. Need to be able set a presice angle somehow. It can be important for angles like 0, 45, 90, ...

also I tried to set the angle to 'zero'. It is just impossible.

@nmanovic
I can try implementing the techique with Shift as I suggested before.

Please implement a standard option for a popular graphical editor. I believe if rotation isn't 0, it should be displayed as an attribute on the side panel as well. At least for occluded we have a button.

@nmanovic

Fixed precision.
Implemented snapped rotation (with Shift step is 15 degrees). It is common approach (i.e. Photoshop).

I believe if rotation isn't 0, it should be displayed as an attribute on the side panel as well

I believe on the side panel this information is totally useless (we don't display there x,y,height,width. Isn't it?
For occluded we have a button because there is no other way to switch it.

I'm fine with the solution if it allows me to set precisely at least 0, 15, ... after I have rotated a box. Occluded and outside properties have corresponding shortcuts. In general it is really a good idea to have a "visual" way to setup an angle. The visual element should have a hint how to do the action using shortcuts. Also rotation is implemented as an attribute thus it is one more reason to have it on the side panel. Just believe me that it isn't useless. But I'm OK to way a feedback from our users before implementing that. It is up to you. Make a decision by yourself.

@bsekachev , Is 360 a valid value?

@aschernov @TOsmanov

Could you please update documentation when the patch is available for you on the internal server?

@dvkruchinin

Could you please prepare some tests to cover the new code and features?

• Check that bounding boxes can be rotated
• Check interpolation, merging/splitting rotated shapes
• Check rotation with hold Shift button
