Michael Niedermayer	e07ac727c1	avcodec/g2meet: Fix framebuf size Currently the code can in some cases draw tiles that hang outside the allocated buffer. This patch increases the buffer size to avoid out of array accesses. An alternative would be to fail if such tiles are encountered. I do not know if any valid files use such hanging tiles.
