Problem

• I'm always frustrated when matplotlib.patches.Rectangle does not round the corners of the rectangle because it requires padding and other rectangle-irrelevant values.
• I would like it if there is a clsas or method like matplotlib.patches.RoundedRectangle(xy, width, height, corner_radius, **kwargs) that can take any radius <= min(width, height) because matplotlib.patches.FancyBboxPatch does not round the rectangle as much as possible.
• Here is a sample image of what I am asking for
  

Proposed solution

Please add/implement matplotlib.patches.RoundedRectangle(xy, width, height, corner_radius, **kwargs)
