Commit 9c6d5222 by Alexis Hetu Committed by Nicolas Capens
Options

Add support for borders around textures.

Borders are required to support seamless cubemap sampling. Subsequent patches will fill the borders with pixels from adjacent cube faces. The border is expressed in pixels and is added on all edges, resulting in an image of dimensions (width + 2 * border) x (height + 2 * border). The surface still exposes dimensions of width x height through the API and points to the same pixel when locked.
