1. Polygon((0, 0), (13, 0), (13, 6), (0, 6)) → AreaBee, f, g, h, i
2. PointIn(AreaBee) → PointBee
3. Segment((0, 0), (x(PointBee), 0)) → xCoord
4. Segment((x(PointBee), 0), (x(PointBee), y(PointBee))) → yCoord
5. Point(yAxis) → F
6. Polygon(Zip[PixelsToPoint[Corner[1], Corner[3], Corner[5], A], A, {(pixelsLeft, pixelsTop), (pixelsLeft, y(Corner[5]) - pixelsBottom), Corner[5] - (pixelsRight, pixelsBottom), (x(Corner[5]) - pixelsRight, pixelsTop)}]) → borderBox
7. Vertex(borderBox, 1) → cornerTopLeft
8. Vertex(borderBox, 3) → cornerBottomRight
9. Segment((0, 0), (0, y(cornerTopLeft))) → axisY
10. Segment((0, 0), (x(cornerBottomRight), 0)) → axisX
11. Corner(5) → appletSize
