1. There are two types of "Gear" icon in PhotoLine that could be simplified to one single icon.
2. There are a lot of confusions with "Gear" icon sizes in different parts of PhotoLine tools and windows:
"200052 IDP_FUNCTION" used in bottom toolbar "Layer List" panel. Uses 15/17/19 grid. No problem here, but for unknown reason it require 19x19px transparent background layer to preserve correct size.
"38298 IDS_PRESET" used in "Presets" (including presets in Adjustment Layer mini toolbar).
Problem: "Presets" windows use 14/16/18 grid and don't preserves pixel perfect look from icon source with 15/17/19 grid.
"18788" Used in Browse -> Browse Settings menu. Uses 15/17/19 grid. Seems no problem here.
"10002 Einstellungen" used in "PhotoLine -> Preferences" menu icon. Also used in Levels Auto Correction window icon.
Problem: In Levels Auto Correction it uses 14/16/18 grid and don't preserves pixel perfect look from icon source with 15/17/19 grid. Icon looks too small in Levels Auto Correction and impossible to adjust separately because same icon source used in other places.
A simple fix for this problem - don't use same gear icon source in multiple places:
1. Use "10002 Einstellungen" source ONLY for 13/15/19 icons (for menu and global icons toolbar).
2. Use separate Einstellungen icon source for 16 px (for Adjustment Layer Windows, Presets, Curves, Levels, Levels Auto correction (similar as "38298 IDS_PRESET" and "18788")
3. Use separate Einstellungen icon source source for Tiny Adjustment Layers toolbar (similar as 200074, 200073, 200071 IDP_COLORPICK_TITLE)
"Function" is not used directly but it is only a source for virtual copies 200052 IDP_FUNCTION and 20032 IDS_LAYERMOVETOOL_EXTENDED
