WS2812B (neopixel) and Graphics lib: custom matrix configuration

I see - I think that could work, but I'd have to reassemble my module differently:

00 01 02 03  16 17 18 19  32 33 34 35
07 06 05 04  23 22 21 20  39 38 37 36
08 09 10 11  24 25 26 27  40 41 42 43
15 14 13 12  31 30 29 28  47 46 45 44

//TO

00 01 02 03  
07 06 05 04  
08 09 10 11  
15 14 13 12  

16 17 18 19
23 22 21 20
24 25 26 27
31 30 29 28

...

However, being rotated, I don't think doing

leds.drawString("123")

will draw expectedly something like

/*
\\\\\\\\\\\\\\\\\
\\\ 123       \\\
\\\\\\\\\\\\\\\\\
*/

but instead will create a rotated version of

/////////
// 123 //
//     //
//     //
//     //
//     //
//     //
/////////

Would work for fillRect or lines I think, but I need to draw text...

Thanks again!
