+/**
+ * The arduino GOS implementation is similar to the bare metal raw32 gos implementation.
+ * It uses cooperative multi-tasking. Be careful
+ * 	when writing device drivers not to disturb the assumptions this creates by performing
+ * 	call-backs to uGFX code unless you define the INTERRUPTS_OFF() and INTERRUPTS_ON() macros.
+ * 	It still requires some C runtime library support...
+ * 		enough startup to initialise the stack, interrupts, static data etc and call main().
+ * 		setjmp() and longjmp()			- for threading
+ * 		memcpy()						- for heap and threading
+ * 		malloc(), realloc and free()	- if GOS_RAW_HEAP_SIZE == 0
+ *
+ * 	You must also define the following routines in your own code so that timing functions will work...
+ * 		systemticks_t gfxSystemTicks(void);
+ *		systemticks_t gfxMillisecondsToTicks(delaytime_t ms);
