// Text Entry controls are notepad-like windows that hold text. 
// They have a border around them and typically hold editable text information.
// In this demo we create a very simple text entry window. It holds one
// line of text and is editable. Typing more text will fill the window with
// text and as you hit the end the text will scroll. 
// The cursor can be moved
// around with arrow keys or positioned with the mouse. Clicking and dragging
// will select text. Right clicking in
// a text edit window will open a cut/copy/paste dropdown, and the windows
// keyboard commands will work as well (ctrl-c/ctrl-v).	Some other windows
// keys work as well (home, delete, end).
// When URL's are displayed in TextEntry windows they become clickable, and
// will open a browser when clicked.
