"""Helper class to read overscan string and calculate output resolution.
It is possible to enter single value for both width and heigh or two values

define output size for input size.
### Example
For input size: 2200px
| String | Output | Description |
|----------|--------|-------------------------------------------------|
| "" | 2200px | Empty string does nothing. |
| "10%" | 220px | Explicit percent size. |
| "-10%" | 1980px | Relative percent size (decrease). |
| "+10%" | 2420px | Relative percent size (increase). |
| "-10%+" | 2000px | Relative percent size to output size. |
| "300px" | 300px | Explicit output size cropped or expanded. |
| "-300px" | 1900px | Relative pixel size (decrease). |
| "+300px" | 2500px | Relative pixel size (increase). |
| "300" | 300px | Value without "%" and "px" is used as has "px". |
Value without sign (+/-) in is always explicit and value with sign is
relative. Output size for "200px" and "+200px" are not the same.
Values "0", "0px" or "0%" are ignored.
All values that cause output resolution smaller than 1 pixel are invalid.
Value "-10%+" is a special case which says that input's resolution is
bigger by 10% than expected output.
It is possible to combine these variants to define different output for
width and height.
Resolution: 2000px 1000px
