2007 - Tasks

Ellipses:
- Random colors
- One ellipse in the client area of the window at the beginning
- A clicked ellipse is divided into two smaller ellipses
  - Each "child" ellipse takes a half of the "parent's" rectangle
  - Divide the rectangle using a bigger dimension always (to prefer ellipses resembling circles)
Properties of the form:
- Client area is transparent (excluding ellipses)
- The size of the form is fixed, do not allow the user to change its size in any way
- On the caption bar display RGB values of the color of an ellipse at the cursor's position
Using Graphics and DCs is forbidden (do not draw anything, use properties of controls)
Hints:
- Form's properties: BackColor, TransparencyKey
- Form's properties: FormBorderStyle, MinimizeBox, MaximizeBox
- Form.Controls.Add(), Form.Controls.Remove()
- the Random class, Color.FromARGB()
- Control's properties: BackColor, Region
- Control's events: MouseMove, Click
- ```
System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath();
path.AddEllipse(rc);
control.Region = new Region(path);
```
