This reverts commit 382ea73f15.
Reason for revert: breaking the non-Metal iOS bots
Original change's description:
> Fixed GLSL ES compilation error in GLTestAtlasTextRenderer
>
> The test was issuing GL code without precision modifiers in a GLSL
> ES context. This wasn't being detected as a fatal error (which is
> a separate issue that should probably be addressed) but was
> resulting in errors being logged from dm on (at least)
> Test-iOS-Clang-iPhone6-GPU-PowerVRGX6450-arm64-Release-All-Metal.
