[PATCH] Add nodata value/transparency support to GIF file creation
Reported by: | Owned by: | Mateusz Łoskot | |

Description (last modified by )
GIF writing currently does not have any kind of nodata value support, but this can be done in the form of a 'transparent' value (I believe it is actually called a 'background' value). It would likely be implemented similarly to the PNG nodata value support in its CreateCopy method.
