Title: variable parsing in watermark position

Useful, when your want to change watermark position dynamically and without duplicating locations. =)

```
location ~ /(right|left|center)/ {
image_filter watermark;
image_filter_watermark watermark.png;
image_filter_watermark_position center-$1; # choose between center-right and ....
}
```
