⚠️ Potential issue

Fix the rectangle drawing bug.

There's an error in Line 17 where y + w should be y + h for drawing the left vertical line of the rectangle.

-   |> Render::drawLine(x, y, x, y + w)
+   |> Render::drawLine(x, y, x, y + h)

🤖 Prompt for AI Agents 
In examples/starrect.pics around lines 13 to 18, the rectangle drawing function
uses y + w instead of y + h on line 17, causing the left vertical line to be
drawn incorrectly. Change y + w to y + h in the call to Render::drawLine on line
17 to correctly draw the left vertical edge of the rectangle.
