Summary

Points in 2D have an x- and y-coordinate. In Esenthel you will use the class Vec2 to store a point.
The class Vec2 has a function draw(Color) to draw a point on the screen.
You can do math with Vec2, just as with an ordinary number.
Vec2(0,0) will always be the middle of the screen.
The borders of the screen can be calculated with D.w() and D.h().

Exercise

Create an application which draws these points:

A white point in the middle of the screen.
A red point on 0.1 units away from the left border of the screen.
A blue point on 0.2 units from the upper right corner.
A yellow dot on 0.35 units from the lower border of the screen, on 2/3 of the total screen width.
