Pull Request Overview

Adds unbuffered, geometry-shader-free implementations for ellipse drawing and cleans up related context and draw logic.

• Vertex shaders now generate ellipse (filled and outline) geometry on the fly, removing the need for geometry shaders.
• circle.py and context.py updated to eliminate buffering/orphaning and to auto-select segment counts.
• Minor adjustment in rectangle vertex shader for consistent operator grouping.

• Add a brief comment explaining that the geometry is intentionally empty and that all vertex positions are generated in the vertex shader.
