Subject: Use low-level handles when computing descriptor set hashes
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=3122f36e64694f5e3f536fa1cca57bf5a3db5c2f

Use low-level handles when computing descriptor set hashes

The handle of a texture may change due to loading and unloading through
a resource manager.
