If I remember correctly, their text editing control is implemented "from scratch", deriving from Control. The control handles key input, caret positioning and blinking, and much much more.

It can be done, but it would be insanity.

Here's all you need to agree:

Step 1: read the latest Rich Text Format specification (12MB Word document - 279 pages)

Upvoted for linking to the RTF format. I've consulted the spec. It's big. Generating a valid RTF doc from scratch is hard enough. Parsing it and formatting text for display is many times harder.
