This feature needs support for renderable float textures, but the checks were only guaranteeing support for float texture reads. Bug: 68754504 Test: CtsViewTestCases Change-Id: I0ce4a81cb8e09c10a5f1e65234685767a24ef8c4 Merged-In: I0ce4a81cb8e09c10a5f1e65234685767a24ef8c4 (cherry picked from commit 8472ac67fd1d815022874f5addace0c4334ae9f6) (cherry picked from commit 8dc7f8275e5ba9004d219d7d7d990e91fc702095)
