+// There is a bug on the Adreno 420 driver where reinterpret casts can destroy a variable.  We need to replace all instances that look like this:
+//      floatBitsToInt(Temp2);
+// We do not need to change cases that evaluate an expression within the cast operation, like so:
+//      floatBitsToInt(Temp2 + 1.0f);
