Implement Heat Map

[HarukaMa]

highlight the colors darker if that number goes high

It's a Heat Map.

Would that be possible to get in PH3 or are you not looking for any graphical changes to the tree view?

The support is already there for drawing individual cells (TreeNewCustomDraw) as a heat map (just like PH already does for the CPU graphs on the process list).

A heat map for something like individual cpu cores works very well (something we do need to implement) but doesn't make any sense when the concept is applied to individual processes.

For example benchmarking programs, diagnostic tools, games and various other things will always show a 'dark' color for high system usage but that's exactly what they were designed to do so what's the benefit?

@dmex Your description only covers the expected processes, but not unexpected ones. Say I have one process that is going haywire and consuming a lot of CPU and memory, and being able to quickly locate such process could be very helpful. I know you can always sort by columns, but with tree view you can have a better overview about the environment.

My feeling is that this tool is meant to be used by advanced users, so people should be able to tell which process should use such resources and which shouldn't (i.e. you can ignore that people would just seeing dark colors and kill the process regardless what it is).
