Initialize uninitialized GLSL arrays in a for loop Previously, creating nodes for initializing each single array element could result in memory bloat during translation when dealing with large arrays. The resulting shader could also end up very long. Initialize most arrays using a simple for loop instead. The loop is compatible with ESSL 1.00 Appendix A limitations. An exception is made for fragment outputs, so that they are not indexed by non-constant values. On some platforms using the a loop to initialize variables can cause problems, so we also have a compiler flag for turning this behavior off. The flag was already added earlier for a staggered rollout of this functionality.
