From: Nicolas Boichat <drink...@chromium.org>
Existing image loader code supports creating images only for window
surfaces. Moreover droid_create_surface() passes wrong surface type to
dri2_get_dri_config(), resulting in incorrect configs being returned for
pbuffers. This patch fixes these issues.
In addition, the config generation code is fixed to include single
buffered contexts required for pbuffers and make sure that generated
configs support only surfaces which can handle their supported buffering
modes.
