* Fix 'RGB parameters out of range' with psychedelic colors
* Fix 'edit-find' icon name
* BlockAnalyzer::drawBackground(): do not attempt to paint on a null background
* Use qBound()
(Well, except Nyanalyzer and Rainbow dash because they are already colourful enough.)
I have added functionality for any 2D analyzer to change any part of its colour palatte with the frequency content of the music, in the same way that Moodbars do.
I find this gives the analyzer a sort of "third dimention".
This is built into Analyzer::Base, so all analyzers can use it and override it as they please. I have thus added support for Block, Boom, Turbine, Sonogram, and Bar, however Boom and Block seem to look the best in my opinion.
This is of course all optional and is toggled by a checkbox in the context menu for the analyzer, disabled by default.
I have not been able to measure any increase in CPU activity with this enabled, even at 60fps.
The analyzers are sent new buffers of audio data to process each time
they pass through the gst pipeline. Different file formats and bit depths/
sample rates can change the size of these buffers, in some cases making them
large and therefore infrequent. This causes choppiness in the analyzer
as it is not getting new data with every frame. This patch chunks the buffers
coming off the pipeline to correspond with the framerate of the analyzer.
