  59 /* Frame buffer stride
  60  *
  61  * Stride describes the amount that you need to increment to get to the next
  62  *  line.  For screens that have the pixels in contiguous horizontal strips
  63  *  stride should be equal to the image width.
  64  *
  65  *      For example, if the screen pixels are layed out as follows:
  66  *
  67  *                  width0  width1  width2                      widthX-1
  68  *                  ------  ------  ------  ------------------  --------
  69  *      height0 |   pixel0  pixel1  pixel2  ---------------->   pixelX-1
  70  *      height1 |   pixelX
  71  *
  72  *      then you need to add X pixels to get to the next line. (the next line
  73  *      in this case is height1).
  74  *
  75  * Similarly, if the screen has the pixels in contiguous vertical strips
  76  *  the stride would be equal to the image height.
  77  *
  78  *      For example if the screen pixels are layed out as follows:
  79  *
  80  *                      width0  width1
  81  *                      ------  ------
  82  *      height0     |   pixel0  pixelY
  83  *      height1     |   pixel1
  84  *      height2     |   pixel2
  85  *         |        |     |
  86  *        \|/       |    \|/
  87  *      heightY-1   |   pixelY-1
  88  *
  89  *      then you would need to add Y pixels to get to the next line (the next
  90  *      line in this case is from width0 to width1).
  91  *
  92  * The remote might have a different stride than the main screen so the screen
  93  *  number needs to be passed to the STRIDE macro so that the appropriate height
  94  *  or width can be passed to the lcd_bitmap, or lcd_remote_bitmap calls.
  95  *
  96  * STRIDE_REMOTE and STRIDE_MAIN should never be used when it is not clear whether
  97  *  lcd_remote_bitmap calls or lcd_bitmap calls are being made (for example the
  98  *  screens api).
  99  *
 100  * Screen should always use the screen_type enum that is at the top of this
 101  *  header.
