/*
Color definitions in ImGui are a good starting point,
but do not cover all the intricacies of Spectrum's possible colors
in controls and widgets.

One big difference is that ImGui communicates widget activity
(hover, pressed) with their background, while spectrum uses a mix
of background and border, with border being the most common choice.

Because of this, we reference extra colors in spectrum from
imgui_widgets.cpp directly. Theme-dependent colors are accessed at
runtime via Spectrum::Colors (a pointer swapped by SetTheme()).
