[OpenJDK 2D-Dev] [9] request for review: 8085910: OGL text renderer: gamma lut cleanup

[Andrew Brygin]

Hello Sergey, and Phil,

  could you please review a fix for CR 8085910?

Bug: https://bugs.openjdk.java.net/browse/JDK-8085910
Webrev: http://cr.openjdk.java.net/~bae/8085910/9/webrev.00/

  This fix just removes the code related to gamma LUTs from
  ogl text renderer. This code is not needed anymore because
  now we use pow() instead of the lookup textures in the lcd
  shader.

  Please take a look.

Thanks,
Andrew.
