    windows: add support for system theme · 956b7f7d
    Aline Gondim Santos authored
    Use registry
    "HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion
    /Themes/Personalize/AppsUseLightTheme"
    to check if system theme is supported and if it is dark or
    light.
    
    Removes "EnableDarkTheme" in favor of "AppTheme".
    
    Requires Windows SDK version 10.0.18362.0 to build with
    system theme support.
    
    Note: This does not watch for changes in system theme in
    runtime as the support for it requires Windows Runtime
    version 10.0.10240.0.
    
    GitLab: #723
