Workaround: MacOS does not have access to glClipControl. Because the lower range of the 32F buffer is not available using this workaround, the improvements to depth behavior from depth reversal will be limited on MacOS. Behavior is equivalent to reversed depth on a 24UINT buffer; Better than stock, but not dramatically.
