Fix for float constant precision in the GLSL backend. Increase the precision of floating point values written out via std::ostringstream. 8 digits is not sufficient to represent all floating point values. Note: the reason the locale test was modified is because it was using a value of 1.9, which has no exact fp32 representation. Increasing the precision causes it to print as 1.8999998 instead of 1.9, failing the test. I've adjusted the value to 1.5, since this does have an exact fp32 representation. (However, note that I couldn't get the test to fail when I removed the locale setting, with either 1.9 or 1.5. Perhaps the locale is being handled at a different level.)
