How to transform the canvas objects while keeping opposite side fixed?
Briefly

The main issue in the canvas editor lies in the resizing functionality, which incorrectly resizes objects from the center instead of from the edge being manipulated. To achieve the desired behavior, the resizing logic must incorporate the edge handle's position and account for the current rotation of the object. Implementing specific calculations for width and height adjustments based on mouse movement relative to the object's bounding box is essential. This approach will ensure a more intuitive and user-friendly experience when editing canvas objects.
To resize an object from the edge being dragged, we need to adjust the resizing algorithm to calculate the new width and height based on the cursor position relative to the edge handle.
Implementing a method that takes into account the current rotation and the position of the cursor when calculating the new dimensions is crucial for proper resizing.
Using the mouse's relative position to the object's bounding box allows for precise adjustments based on which handle is being dragged, rather than affecting the object's center.
Maintaining the selected state of an object and showing handles only for the selected object is essential for intuitive user interaction in canvas editing.
