New Spectrogram Appearance

[taylanunver]

I have added a new spectrogram appearance called "Heat". It is a modified version of the color map inferno. It is made to resemble the audio tools in the music industry. To achieve this with minimal performance hit I have created a method to import 1x256 images as palettes. Here are some example spectrograms.

I have also added a unified view of spectrogram and waveform with an opacity slider at the bottom. Spectrogram now also scales vertically to fill container.

Looks good :)

Could you move the opacity setting to Options - Settings - Waveform?
The main interface should only contain stuff used often, and I think most people will probably just use the default value (if it's sensible).

The selected paragraph also needs the opacity...

Can you point me out on which file is responsible for storing settings?

Here's the newly added option in the settings menu.

Can you please add an option to make the merging of the waveform + spectrogram optional?
I just updated to 4.0.12 and I find the merged view very confusing with my color settings (Classic), I prefer to have them one above the other.

Old:

New:

 
The waveform itself, the shot change markers, and the subtitle text are barely readable now.
Decreasing the spectrogram opacity makes it more difficult to see the hot/red spots of the spectrogram.
Having them stacked vertically was much more clear to me.

Unfortunately, I don't have spare time at the moment to add an option myself, so I'll have to downgrade to 4.0.11 in the meantime.

Thank you.
