if You initialize DateTimePicker with year >= 9990 it will crash when handling
paint event

Reproducible: Always

Steps to Reproduce:
1.put DateTimePicker on a form 
2.initialize it with date >= 9990 year
  public Form1()
    dateTimePicker1.Value = new DateTime(9990, 1, 1);
Actual Results:  
exception thrown from function DateTimePicker.CalculateMaxWidth

there is piece of code that adds 10 years to current value of control:

for (int i = 1; i <= 10; i++) {
  text = PartData.GetText (Value.AddYears (i), format);

result of adding 10 years to year 9990 = exception

Expected Results:  
form should appear with DateTimePicker set to date 9990-1-1

this also happens with date set by binding
