Author: Kenneth Graunke <kenn...@whitecape.org> Date: Thu Aug 22 01:29:11 2013 -0700 meta: Set correct viewport and projection in decompress_texture_image. _mesa_meta_begin() sets up an orthographic project and initializes the viewport based on the current drawbuffer's width and height. This is likely the window size, since it occurs before the meta operation binds any temporary buffers. decompress_texture_image needs the viewport to be the size of the image it's trying to draw. Otherwise, it may only draw part of the image. v2: Actually set the projection properly too.
