Detailed Description ​

cpp
class Theme;
class Theme;

ApplicationTheme holding custom style variables that override the current ImGui style and/or are used separately by various parts of the I3T code.

The Theme holds color information as well as general sizing information.

Themes do have a UI/DPI scaling factor using which relevant sizing variables are scaled when fetched. Changes of the scaling factor are however handled elsewhere (in UIModule).

Themes do hold an association between font keys and actual font names. But fonts are loaded and managed externally (by the FontManager). Currently the Theme cannot load new fonts, but it can change which fonts are used where. // Proposal: (Issue #432) Themes could tell FontManager which fonts to load
