Subject: [PATCH 082/294] Move #if #else #endif for convenience

This is a convenience change. The double '{' created by the #else messes
up Xcode autoindentation.
It won't that way and the fact that useClientState is a const set to
false when SUPPORT_LEGACY_OPENGL, the code inside the if should still
get optimised out by the compiler.
