Vector Editor

The vector editor allows you to draw several primitives, namely:
1 . The line
2nd The surroundings
Three The Duga
4 . Curve of 2nd order
It also allows you to change all the properties of all the primitives (color, position size). There is also the possibility to scalate the whole picture with the help of a mouse scroll. The editor allows you to build touch circles to the circle, as well as cut all objects straight - forming new.
It is remarkable that this editor is written without using the features of the graphic library of the painting primitive. This means that everything is drawn using mathematical calculations and the only function is SetPixel.
This particularity was requested by the project client.
