Partial libpng15 patch

No longer compiles with stable libpng-1.5.5:

./../../wxcommon/wxJPEG.cxx: In function 'void user_error_proc(png_structp, png_const_charp)':
./../../wxcommon/wxJPEG.cxx:524:20: error: invalid use of incomplete type 'png_struct {aka struct png_struct_def}'

Thanks Samuli for the summary of the issue, and links to related bugs and forum post, and for the p.mask message.

> Plus not sure why Bug 324161 is still open

When that bug was open, they were stable versions of dev-scheme/plt-scheme in the tree. So that bug intended to stay open until a version of dev-scheme/racket gets stabilized.

Stable keywords were dropped for plt-scheme due to libpng-1.4 bump, so I think you're right, that bug could be closed.
