After learning about streams and all the snazzy Java 8 features around parallel processing, the map-from-BMP code came up as a good candidate to consider trying it out on. It is, fundamentally, an algorithm composed of a series of steps, which is exactly what the stream/map/filter/reduce APIs are built for.
And though it may not be a very heavily used part of the editor, it is somewhat performance-intensive, and would be a great place to learn the skills, so why not?
Sped up the Shazam() function, which is what is running when the "Reticulating splines" title appears. Put the whole main loop in a lambda expression, and put that in a parallel stream. The results are impressive. For a low amount of work, it's now parallel, and on my 4 GHz Core i5 quad-core, runs in 32.3% of the original time. That includes a little bit of single-threaded setup and teardown work, to work around the arrays being 2D in that code in general, but the stream working on and producing a 1D array.
I could probably incorporate the createBIQMap method (or most of it, anyway - maybe not the call to biqFile.createMap) into a lambda expression, too.
Sped up for 1.23. Quad-core now takes 1/3 the time; dual-core takes 55-60% of the time.
