Uniform locations are 32-bit values which the application queries from the driver after a shader program is linked. It seems that Cordy game (possibly all Unity based apps) store the returned location as 16-bit value. Intel driver returns location values in the upper 16-bit range :( This is a workaround for this issue, when a program is linked we check the locations of all uniforms, if all locations are within the upper 16-bit range (as with Intel driver) we shift the location value before returning to the application. Also override all functions which take a location parameter and do the reverse shift before sending a location value to the host. Change-Id: I234aaafe3313774b5da79eb1dac713b89b10ad60
