Detailed Description

Structure to represent arbitrary-sized 9-patches.

While expanding a 3x3 rect is simple enough and has its purpose, this is an attempt to generalize the idea to a struct representing a 9-patch like this, such that areas 1, 2, 3 and 4 have no null dimensions and don't overlap:

margins.left  margins.right            │  Such as:
╭───┴───╮     ╭─┴─╮                    │
╔═══════╤═════╤═══╗ ╮                  │    1) margins.left + margins.right  <= width (patch_rect)
║   1   │  6  │ 2 ║ ├─ margins.top     │
╟───────┼─────┼───╢ ╯                  │    2) margins.top  + margins.bottom <= height(patch_rect)
║   5   │  0  │ 7 ║                    │
║       │     │   ║                    │    3) margins values are inclusive, in number of tiles
╟───────┼─────┼───╢ ╮                  │
║       │     │   ║ │                  │
║   4   │  8  │ 3 ║ ├─ margins.bottom  │
║       │     │   ║ │                  │
╚═══════╧═════╧═══╝ ╯                  │
╰────────┬────────╯                    │
     patch_rect                        │
