• enables the rotate handle with a 'grab' icon for hovering style for rectangles
• adds function for calculating the rotation between rotated bounding boxes
• Stores the rotation value as a detection attribute called 'rotation'
• Added logic for reserved fields for detection and track attributes
• All bboxes should be stored as an axis-aligned bbox with a rotation in radians CCW about the center in radians
• If the rotation isn't default, a small arrow is drawn on the 'right' side of the bbox

TODO:

• fix that resizing is recalculating the size of the base bbox, when you resize the rotation doesn't change but the size changes. To fix this I think I need to check the rotated new version size vs the previous size and that changes the center point but not the rotation.
  • need to check points and see if the points between old and new are in a line that has a rotation that matches the rotation value. This is because when adjusting the width/height it's still a box so if the angle between the resized points is the same we know it's a size adjustment and not a rotation. I.E calculate the vector (directionality of points and compare.
