Description

This is sometimes useful when doing advanced symbology, for example when you need symbols on both sides of the line, but not in the same place, or when you need a symbol that must show where are the dashes of a line. See the following picture

as there is the offset to allow place the markers on one side of the line, an offset to start after the beginning of the line would be needed.

To notice that the X offset that is possible to define of the markers does not solve the issue:

+) if the option "rotate marker" is not active, the offeset will result in an horizontal shift

+) if the option "rotate marker" is active, the result is similar to the one requested, the problem is that the shift does not take into account the line bends, resulting in errors

[FEATURE] Add option for shifting markers in marker line style a set distance along the line. Supports delaying the start of markers placed at intervals, or placing markers a set distance before/after the first/last vertex (fix #9000)
