This series implements ARB_copy_image in i965 in two steps: First, we
provide a meta implementation that handles the cases when both textures are
uncompressed and we can leverage the already-existing code for
BlitFramebuffers. The other case, when at least one texture is compressed,
is handled by calling into the blitter hardware.
Jason Ekstrand (5):
Add GL API support for ARB_copy_image
mesa/meta: Make _mesa_meta_bind_fbo_image also take a framebuffer
target
mesa/meta: Add support for storing the current read buffer
mesa/meta: Add a partial implementation of CopyImageSubData
i965: Add support for ARB_copy_image
