[vtk-developers] VTK_USE_GLSL_SHADERS default

[Moreland, Kenneth]

Does anyone have an objection if I change the default value of the
VTK_USE_GLSL_SHADERS option to ON?  VTK compiles and links the GLSL
shaders just fine with nothing but the OpenGL 1.1 libraries.  It builds
even if the GLSL shaders are not available on the compiling platform.
