Free display arrangement instead grid

[davidkennedydev]

Today I'm using 2 displays and another external computer that I was connecting using Barrier and it's amazing!
However now I had to change my setup arrangement and start to get issues with the grid display arrangement, at Gnome, there is a way to arrange displays freely:

Barrier just has a grid for arrangement and seems that they don't take into account second displays the grid just look to the host machine as a single display computer:

There is a way to have a similar free display configuration instead of a grid and take into account multiple displays at one computer?

Looking for changes

GUI

It's a grid UI element but could be a free drag and drop element

barrier/src/gui/src/ServerConfig.cpp

Lines 29 to 41 in fc045fc

	static const struct
	{
	int x;
	int y;
	const char* name;
	} neighbourDirs[] =
	{
	{ 1, 0, "right" },
	{ -1, 0, "left" },
	{ 0, -1, "up" },
	{ 0, 1, "down" },
	};

Server

IScreen seems already enough abstract because it has as parameters a left-top first-pixel position, width, and height:

barrier/src/lib/server/BaseClientProxy.h

Lines 64 to 65 in fc045fc

	virtual void getShape(SInt32& x, SInt32& y,
	SInt32& width, SInt32& height) const = 0;

The server implementation seems to use these parameters generically:

barrier/src/lib/server/Server.cpp

Lines 450 to 461 in fc045fc

	void
	Server::switchScreen(BaseClientProxy* dst,
	SInt32 x, SInt32 y, bool forScreensaver)
	{
	assert(dst != NULL);
	#ifndef NDEBUG
	{
	SInt32 dx, dy, dw, dh;
	dst->getShape(dx, dy, dw, dh);
	assert(x >= dx && y >= dy && x < dx + dw && y < dy + dh);
	}

TL;DR

Maybe the main blockers existing today are the rigid GUI and the server's inability to treat multiple displays in one same machine.

"The inability to treat multiple displays on the same machine" seems more complex to fix but could be done in a separate effort.
