Summary: wxPNGHandler::DoCanRead wrong magic number

Initial Comment:
wxPNGHandler::DoCanRead in imagpng.cpp tests for magic number 0x0211. Correct one: 137 (decimal, should be 0x089). wx.NET imghandler.cxx includes a small subclass that fixes problems with image detection within the HTML control.

do you have a bug which shows a problem at that line ? looking at the code
in the 2.8 branch or on cvs head, I don't see a problem, it doesn't compare
the hex 211, but it compares the octal 211 which is decimal 137, so the
code seems correct to me

Best,

Stefan
