/**
 * 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);
