Bug 223314

https://www.khronos.org/registry/webgl/sdk/tests/conformance/extensions/oes-texture-float.html?webglVersion=1&quiet=0&quick=1 This test verifies the functionality of the OES_texture_float and WEBGL_color_buffer_float extensions, if available. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
