Update the logic of the function GetIconResourceAsBitmap in class Sca… (

dotnet#10459)

Using function "GetIconResourceAsBitmap(Type type, string resource, Size size)" instead of "GetIconResourceAsBitmap(Type type, string resource, int dpi)" when initial Image "GlyphImageClosed" and "GlyphImageOpened" becasue these images are smaller than the standard size, they are 10x10. We need this custom size to scale them correctly.
