REVISION SUMMARY Create them only on-demand (e.g. when the menu opens or the DecorationRole is queried) and also use KConfig::SimpleConfig as we're passing in an absolute file path anyway. TEST PLAN On Kate startup KColorSchemeManager went from 12% cost to 2.6% and saves around 40ms Kate startup time for me. Previews are still generated properly when I enter the menu. A `QComboBox` using the model still gets its previews generated when it reads the `DecorationRole` REPOSITORY R265 KConfigWidgets BRANCH ondemandpreview REVISION DETAIL https://phabricator.kde.org/D22531 AFFECTED FILES src/kcolorschememanager.cpp src/kcolorschememanager_p.h To: broulik, #frameworks Cc: kde-frameworks-devel, LeGast00n, sbergeron, michaelh, ngraham, bruns
