Subject: [PATCH] media-libs/libgfx: Update sources

External libraries, specifically libpng, as well as C++ as a whole, has
been updated a lot since this was released in 2005. This patch will
allow the package to compile; however, it does not update the build
system, update the tests, nor change the package in non-trivial ways.
The package cannot compile the tests because the build system cannot
find fltk. Therefore, I cannot testify whether the package will still
act as intended since I have not tested it.
