commit 6ffa4b88be5ac1580d29193b6cd3d216415d9be2

    glamor: Added in an optimization to copy area that uploads the data directly to the destination similar to what EXA did
    
    For instances where the destination has a FBO but the source doesn't,
    the code now just puts the data that was in source directly into
    destination through glamor_upload_sub_pixmap_to_texture.  This is the
    same way that EXA works in this case as well.

commit 654e1536a6d6539dcc30d9151122536c1807f34a

    glamor: Add in support for the stride parameter when uploading texture data
    
    The method __glamor_upload_pixmap_to_texture was updated to support a
    stride parameter for the data being uploaded to a texture.  This
    required correctly setting the alignment from 4 to a value based on the
    depth of the data and also required setting GL_UNPACK_ROW_LENGTH based
    on both the stride and the alignment.
    
    The stride parameter was also updated in glamor_put_image to be
    correctly specified, the old values would cause the xserver to crash.
