#1241 Folding line color and size

[mLipok]

When you fold a group of code then you see only first line of this code.
Above this line of code you will see additional FOLDING LINE (just line -- not line of code).

My feature request is:
To have possibility to change FOLDING LINE Color, and height.

Why Color ? because many users use dark themes and this FOLDING LINE is alomst invisible.
Why height ? Did you use SciTE on 4K montior, just try and this became a quite resonable Feature ?

Remark:
instead of the height parameter, you could just cause the whole further part of the line (trailing space) to be marked with a different color.

Maybe two colors can be added to set the foreground color for vertical line and horizontal line. If the line color is same as foreground background color for default style, the line can be omited.

Increase stroke width of folder marker and folder line has problem with box-tree scheme: burr at corner (some coordinates need adjust).

Anothor issue is zooming, the fold margin width and stroke width should been zoomed when the document is zoomed. Picture made on a 200% display should looks similar to picture made on a 100% display zoomed at 200%.

The line is drawn in the foreground colour of STYLE_DEFAULT so should adapt to a dark mode.

A height setting could be included if someone provides a reasonable implementation.

ah....
by change this following line
style..32=$(font.base),back:#E2EDE0
to:
style..32=$(font.base),fore:#FF0000,back:#E2EDE0

solve it.

As to Height setting I think this above fix is sufficent for my eyes.
Lets see what @Zufu Liu will say about.

Added SC_ELEMENT_FOLD_LINE to change colour.
