This is commit of Simon Detheridge's pull request "osx-opencl" with a few modifications.

Browse Source 
-If we change OpenCLWrapper to capture build log errors, we don't need to manually concat them in RendererCL because the overridden ErrorReport() function already concatenates the errors from both classes.

-Do not define T in OpenCL programs. We already have real_t to handle this.

-Do keep the casting to real_t. However this should not be necessary because there is a command line option to do this automatically which we already use: -cl-single-precision-constant. The only reason we do this is because the Apple OpenCL compiler does not follow the standard and obviously ignores this option. Absolutely awful.

-Fix a few improper casts in the CircleTrans1 and GlynnSim1 variations.

-Add an automated OpenCL program build tester to EmberTester, as well as a cast checker.
