-// static_ex.h : This class extends static control functionality to display
-// formatted text and hyper-links
-//
-// Currently it supports the following formatting options:
-//   bold         - <b>bold</b>
-//   italic       - <i>italic</i>
-//   underscore   - <u>underlined</u>
-//   color        - <color=ff0000>red</color>
-//   size         - <size=14>14 points text</size>
-//   hyperlink    - <a=http://www.google.com>click here</a>
-// formatting options could be nested (except hyperlink)
-//
-// Some fonts (including Tahoma) often overhang one pixel (for example in "W")
-// so StaticEx is created with default 1 pixel margin on the left and right,
-// use set_margins() to overwrite default values if you need to.
