-----------------------------------------------------------------------
The necessity of this function is pretty silly. I would like lighthouse
to be color-aware of the user's IDA theme such that it selects reasonable
colors that maintain readability.
Since there is no supported way to probe the palette & colors in use by
IDA, we must get creative. This function attempts to locate an IDA
disassembly view, and take a screenshot of said widget. It will then
attempt to extract the color of a single background pixel (hopefully).
