/*
* Set predefined flextile layout.
*
* The arg int value is a binary representation of the setup where certain bits have different
* meanings, similar to how Linux permissions work.
*
* The first two bits represents the stack axis, bits 3 and 4 the master axis. Bits 5 and 6
* are used to control the layout while bit 7 indicates whether or not the layout is mirrored.
* The 8th bit is reserved while bit 9 through 12 control nmaster with up to 15 clients in the
* master stack.
*
* Bitwise layout:
*
* 0000 (nmaster: 0-15 = clients in master stack)
* 0 (reserved)
* 0 (orientation: 0 = normal, 1 = mirror)
* 00 (layout: 00 = vertical, 01 = horizontal, 10 = centered (vert), 11 = centered (horz))
* 00 (master axis: 00 = left to right, 01 = top to bottom, 10 = monocle, 11 = grid)
* 00 (stack axis: 00 = left to right, 01 = top to bottom, 10 = monocle, 11 = grid)
*
* Examples:
* binary int layout
* --------------------------
* 000000000110 6 monocle
* 000100000110 262 deck layout
* 000100010000 272 bstack layout
* 000100010001 273 bstackhoriz layout
* 000000000111 7 grid layout
* 000100000101 261 default tile layout
* 000100100101 293 centered master
* 000100000111 263 default tile layout with grid stack
* 000100000001 257 columns (col) layout
