| // whose size is 1440x800 at the location (100, 200) in host coordinates. |
| // The format is |
| // |
| // [origin-]widthxheight[*device_scale_factor][#resolutions list] |
| // [/<properties>][@ui-scale] |
| // |
| // where [] are optional: |
| // - |origin| is given in x+y- format. |
| // - |device_scale_factor| is either 2 or 1 (or empty). |
| // - properties can combination of 'o', which adds default overscan insets |
| // (5%), and one rotation property where 'r' is 90 degree clock-wise |
| // (to the 'r'ight) 'u' is 180 degrees ('u'pside-down) and 'l' is |
| // 270 degrees (to the 'l'eft). |
| // - ui-scale is floating value, e.g. @1.5 or @1.25. |
| // - |resolution list| is the list of size that is given in |
| // |width x height| separated by '|'. |
| // |
| // A couple of examples: |
| // "100x100" |
| // 100x100 window at 0,0 origin. 1x device scale factor. no overscan. |
| // no rotation. 1.0 ui scale. |
| // "5+5-300x200*2" |
| // 300x200 window at 5,5 origin. 2x device scale factor. |
| // no overscan, no rotation. 1.0 ui scale. |
| // "300x200/ol" |
| // 300x200 window at 0,0 origin. 1x device scale factor. |
| // with 5% overscan. rotated to left (90 degree counter clockwise). |
| // 1.0 ui scale. |
| // "10+20-300x200/u@1.5" |
| // 300x200 window at 10,20 origin. 1x device scale factor. |
| // no overscan. flipped upside-down (180 degree) and 1.5 ui scale. |
| // "200x100#300x200|200x100|100x100" |
| // 200x100 window at 0,0 origin, with 3 possible resolutions, |
| // 300x200, 200x100 and 100x100. |
