FS#82 - php gd rotation functions vs upstream
User who did this - Pierre Joye (Pierre)

----------
"Internal PHP gd has some rotation functions that are not in upstream gd. I always wondered why these weren’t integrated into upstream?"

I added these functions (imagerotate from php) before I took the hand on the official libgd project. Unlike the current gd function in libgd, imagerotate uses a rotate by shear method and gives a better result (compared to nearest pixel filter).

GD 2.1.0 will introduce a set of filter to be used with image transformation (rotation, shear, resize) and both php's libgd and the official version will support them.
