[FFmpeg-devel] libavcodec/exr : add support for compression in tile

[Martin Vignali]

Hello,

In attach a patch, in order to enable compression in tile.

With modification inside PIZ uncompress, B44 uncompress, and PXR24
uncompress.

s->xdelta is replace by s->xsize.
For scanline it doesn't make any change, because s->xsize == s->xdelta.
In tile s->xsize is the width of the tile or less (if we are at the right
of the datawindow).

RLE, ZIP1, ZIP16 works without modification inside uncompress function.


Tile PIZ sample GoldenGate.exr works now
