Detailed Description

Command for drawing a rectangle.

Encapsulates all parameters needed to draw a rectangle (axis-aligned). Constructed via RectangleBuilder.

Member Semantics:

top_left: Top-left corner coordinate
bottom_right: Bottom-right corner coordinate
color: Rectangle color (border and fill use same color)
border_width: Thickness of rectangle outline
fill: Empty (outline only) or Full (solid fill)

Coordinate Constraints:

Assumes bottom_right.x >= top_left.x and bottom_right.y >= top_left.y
Inverted coordinates (e.g., top_left.x > bottom_right.x) produce undefined results
Zero-area rectangles (top_left == bottom_right) render as single point

Fill Behavior:

DrawFill::Empty: 4 border lines only (interior transparent)
DrawFill::Full: Border + interior filled with horizontal scan lines
