Hi, I was looking through the code, and I found a couple of things that I
didn't quite understand:
- why does GetRgb use strstr with color names?
- when checking for d-links in CheckImage (lines 821 and 852) why does it
use strcmp? doesn't seem to match the comments
- also in CheckImage, what's up with the empty ifs at line 861?
- getTextNode doesn't seem to do anything for non-text nodes, shouldn't the
content traversal be in an "else" branch?

Could somebody take a look?
