/* Tags
* In a traditional dwm the number of tags in use can be changed simply by changing the number
* of strings in the tags array. This build does things a bit different which has some added
* benefits. If you need to change the number of tags here then change the NUMTAGS macro in dwm.c.
*
* Examples:
*
* 1) static char *tagicons[][NUMTAGS*2] = {
* [DEFAULT_TAGS] = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I" },
* }
*
* 2) static char *tagicons[][1] = {
* [DEFAULT_TAGS] = { "" },
* }
*
* The first example would result in the tags on the first monitor to be 1 through 9, while the
* tags for the second monitor would be named A through I. A third monitor would start again at
* 1 through 9 while the tags on a fourth monitor would also be named A through I. Note the tags
* count of NUMTAGS*2 in the array initialiser which defines how many tag text / icon exists in
* the array. This can be changed to *3 to add separate icons for a third monitor.
*
* For the second example each tag would be represented as a bullet point. Both cases work the
* same from a technical standpoint - the icon index is derived from the tag index and the monitor
* index. If the icon index is is greater than the number of tag icons then it will wrap around
* until it an icon matches. Similarly if there are two tag icons then it would alternate between
* them. This works seamlessly with alternative tags and alttagsdecoration patches.
*/

* { "Gimp", NULL, NULL, NULL, 1 << 4, 0, -1 },
* { "Firefox", NULL, NULL, NULL, 1 << 7, 0, -1 },
*
* The RULE macro has the default values set for each field allowing you to only
* specify the values that are relevant for your rule, e.g.
*
* RULE(.class = "Gimp", .tags = 1 << 4)
* RULE(.class = "Firefox", .tags = 1 << 7)
*
