Detailed Description

Command for drawing a point (pixel or multi-pixel dot).

Encapsulates all parameters needed to draw a point. Constructed via PointBuilder.

Member Semantics:

• position: Point location in logical coordinates
• color: Pixel color
• pixel_size: Size of the "dot" (Pixel1x1 to Pixel8x8)

Pixel Size Rendering:

• Pixel1x1: Single pixel at position
• Pixel2x2: 2x2 square centered at position (4 pixels total)
• Pixel3x3: 3x3 square centered at position (9 pixels total)
• ... and so on up to Pixel8x8

Centering Behavior:

• For even sizes (2x2, 4x4, etc.), center is top-left of 2x2 center quad
• For odd sizes (1x1, 3x3, etc.), center is exact middle pixel
