Descripti= on

A plasmoid intended to be used on a panel. Inspired by gnome=
-multiload-applet and gkrellm.

Before I decided to write this plasmoid, I considered other monitors. Here&=
#39;s what I found:
- system-monitor:
   * not pixel-perfect: it uses antialiasing and Bezier curves
   * in stacking mode, it adds a few pixels to all values, so a 0 network t=
hroughput still shows 2 belts.
   * impossible to read at a glance due to low contrast and no custom colors
   * shows only basic properties
   * graphs change features depending on size
   * deal-breaker: impossible to set custom height or width
- system-load-viewer: almost there, but no history display
- The Only Right RAM Monitor: too slow and RAM only

This plasmoid attempts to solve all those problems while introducing new on=
es :)
What's fixed in this one:
- many graphs in one applet
- graphs laid out on a grid
- forces graph width or height (depending on mode)
- can force row or column number (depending on mode)
- arbitrary colors for all graph types
- pixel-perfect
- handles runtime CPU/network addition/removal (CPU untested)

Other stuff:
- labels only for network interfaces
- resizable labels
- network transmit graph stacks on top
- C++, a monitor should measure resources, not use them
- no way to disable graphs :)
- no way to reorder graphs
- network interfaces are not sorted
- all CPUs are displayed
- can't change colors for a distinct graph
- will not fit in container if the wrong layout params are selected (forcin=
g a dimension to be more than available)
- the original idea was to synchronize all readings, but it seems impossibl=
e with plasma data engines

It's my first project in Qt, so the code will not be as nice as it coul=
d be. I rewrote the plotter and the layout, so those are the most likely to=
 contain errors/memory leaks. Also, I don't know which of the above pro=
blems need to be solved and which decisions are acceptable, but I'll ha=
ppily apply all fixes to make this accepted.

Testing <= /h1>

Display, layout, configuration, persistence.
