>Description:
Upgrade gd to 2.0.34.
New Upstream Maintainer, Pierre-A. Joye, hosted at http://libgd.org/
I changed up the port to use it's own configure script, and backported
the FreeBSD specific functions gdImageLzw*() & gdImageBigGif*() to use
gdImageGif*() functions. gdImageCreateFromGifSource() & gdImageGifToSink()
did not have any code backing them, so I removed the prototypes.
It should keep the same library extension as 2.0.33. I also modified the
existing scripts to allow GD_FONTS to still work.

- * on the LZW algorithm.) However, miGIF generates data streams that any
- * reasonably sane LZW decompresser will decompress to what we want.
- *
- * miGIF compression uses run length encoding. It compresses horizontal runs
- * of pixels of the same color. This type of compression gives good results
- * on images with many runs, for example images with lines, text and solid
- * shapes on a solid-colored background. It gives little or no compression
- * on images with few runs, for example digital or scanned photos.

- * Algorithm: use open addressing double hashing (no chaining) on the
- * prefix code / next character combination. We do a variant of Knuth's
- * algorithm D (vol. 3, sec. 6.4) along with G. Knott's relatively-prime
- * secondary probe. Here, the modular division first probe is gives way
- * to a faster exclusive-or manipulation. Also do block compression with
- * an adaptive reset, whereby the code table is cleared when the compression
- * ratio decreases, but after the table fills. The variable-length output
- * codes are re-sized at this point, and a special CLEAR code is generated
- * for the decompressor. Late addition: construct the table according to
- * file size for noticeable speed improvement on small files. Please direct
- * questions about this implementation to ames!jaw.
