-/*************************************************************************
- * Description: 
- * 
- * The underlying implementation of the ESP32-HUB75-MatrixPanel-I2S-DMA only
- * supports output to HALF scan panels - which means outputting 
- * two lines at the same time, 16 or 32 rows apart if a 32px or 64px high panel
- * respectively. 
- * This cannot be changed at the DMA layer as it would require a messy and complex 
- * rebuild of the library's internals.
- *
- * However, it is possible to connect QUARTER (i.e. FOUR lines updated in parallel)
- * scan panels to this same library and
- * 'trick' the output to work correctly on these panels by way of adjusting the
- * pixel co-ordinates that are 'sent' to the ESP32-HUB75-MatrixPanel-I2S-DMA
- * library.
- *

-/* Use the Virtual Display class to re-map co-ordinates such that they draw

-# Using this library with 32x16 1/4 Scan Panels
-
-## Problem
-ESP32-HUB75-MatrixPanel-I2S-DMA library will not display output correctly with 'Four Scan' 64x32 1/8 or 32x16 1/4 scan panels such [as this](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-I2S-DMA/issues/154) by default.
-
-## Solution
-It is possible to connect 1/8 scan panels to this library and 'trick' the output to work correctly on these panels by way of adjusting the pixel co-ordinates that are 'sent' to the underlying ESP32-HUB75-MatrixPanel-I2S-DMA library (in this example, it is the 'dmaOutput' class).
