Revert 60236 - Fix WebGL getParameter bug in command buffer. 

GetHelper was turning all getParameter return values into integers, even 
if they should have been floats. By returning false in GetHelper, it 
lets the individual DoGet(Float,Boolean,Integer)v functions skip this 
behavior and return the real value directly.
