Captcha Image Drawing
Captcha is used to prevent automated "bots" from accessing pages by showing an image that a human can read but a computer can't. This is not a full implementation of captcha, only a proof of concept exercise in drawing the image. The C# source does the following:
1. Create the bitmap.
2. Draw a patterned background.
3. Draw some light noise lines.
4. Draw some dark noise lines.
5. Randomly pick a code and draw the letters.
6. Draw additional noise lines that overlap the letters.
7. Stream the image and cleanup.
