Datecrossing Monthcalendar

I've decided to edit the monthcalendar. Currently it's extremely limited as to what it can do. It was written in VS 2012 targetting the .net framework 4.0

Features:

You're able to cross out selected dates
The cross adjusts to the font type

Drawbacks:

Extremely limited as to what it can do

Plans:

My plans are to create a semi-transparent rectangle over the dates

Notes:
-I'm very happy with the ability to paint over this stubborn control. I would like to create more functionality with it, but I'm kinda lost for ideas. So if y'all have any ideas, please pitch them to me.
