Upstream got rid of theme recoloring, but I thought ours worked pretty
good, so I decided to reapply it. This commit also reapplies commit
ee370f0e13.
Actually, upstream's new dark theme blends pretty well with Breeze Dark
under KDE on Arch Linux. Still, our themes will be reintroduced (and set
as default).

\class Theme
|
|
\brief Based on ThemeBase, Theme manages image and icon resources.
|
|
|
|
Theme is a class which manages theme resources.
|
|
It maps sets of ids to the resources and to names of the resources,
|
|
so that they can be loaded/saved from files.
|
|
|
|
Theme adds the Audacity specific images to ThemeBase.
|
|

\class FlowPacker
|
|
\brief Packs rectangular boxes into a rectangle, using simple first fit.
|
|
|
|
This class is currently used by Theme to pack its images into the image
|
|
cache. Perhaps someday we will improve FlowPacker and make it more flexible,
|
|
and use it for toolbar and window layouts too.

\brief Allows us to capture output of the Save .png and 'pipe' it into

our own output function which gives a series of numbers.
