//This special define is made to fix buggy OpenCL compilers on Mac.
//Rendering is much slower there for unknown reasons. Michel traced it down
//to the consec variable which keeps track of how many tries are needed to computer
//a point which is not a bad value. Strangely, keeping this as a local variable
//is slower than keeping it as an element in a global array.
//This is counterintuitive, and lends further weight to the idea that OpenCL on Mac
