/**
 * The raw32 GOS implementation supports any 32 bit processor with or without an
 * 	underlying operating system. 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);
