Decorations drawn by external decorator are smaller that the window reserved for it.

I use windows shadow plugin to draw shadows, and with standard decoration or firedecor it gives exact match, but in this decorator the shadows are between the end of decorations and start of shadow.

Found the reason for it - 4 pix hardcoded in decorator process as delta and is getting always added to the theme settings.

Hi,
yeah, I will add a config parameter to set the delta border.
Unfortunately it is needed, since if the metacity theme has a 0px border the window cannot be resized.

I just found that this change didn't change nonworking shadows here but with both Menta and my UbutuStudio_Legacy theme
https://github.com/lukefromdc/gtk-theme-ubuntustudio-legacy
greatly reduced the prominance of the nontransparent underlying window behind the decorations,
#6
so that it is now visible only at the rounded corners. Interestingly, I still get the ability to resize from just outside the visible border in these two themes.

Note that shadows are not working here with wayfire 0.8.0 on Debian Unstable no matter what the decorator.

Also on fullscreen or tiled windows, the window contents are drawn several px smaller than the inside of the decorations, and the titlebar thus appears to be slightly too long and the desktop or other background beneath is visible through that gap.
