Description
For an ellipse with center (u, v), semi-axis (a, b), angle θ, the circum points can be calculated from parametric equation and 2D rotation:
x = a cost cosθ - b sint sinθ + u
y = a cost sinθ + b sint cosθ + v
t ∈ [0, 2π)
To draw elliptic arc, set t ∈ [start_angle, end_angle].

Research direction
No file, test, or entry point is named. Start by locating the existing ellipse and elliptic-arc drawing APIs and their tests, then compare their supported geometry with the supplied rotated parametric equations. Done means oblique ellipses and arcs render for the stated center, semi-axes, rotation, and angle bounds.
