-**minimal LVGL support**  
-`#define USE_LVGL`  
-to test LVGL a few functions are implemented:  
-`lvgl(sel ...)` general lvgl call  
-each object gets a concurrent number 1 ... N with which you can reference the object
-sel = 0 => initialize LVGL with current display
-sel = 1 => clear screen  
-sel = 2 xp yp xs ys text => create a button. the button press is reported in section >lvb  
-sel = 3 xp yp xs ys => create a slider. the slider move is reported in section >lvs  
-sel = 4 xp yp xs ys min max => create a gauge.    
-set = 5 objnr value => set gauge value.  
-sel = 6 xp yp xs ys text => create a label.  
-sel = 7 objnr text => set label text  
-sel = 8 create a keyboard, just get a look and feel
