/* For PresetComboBox we use bitmaps that are created from images that are already scaled appropriately for Retina
 * (Contrary to the intuition, the `scale` argument for Bitmap's constructor doesn't mean
 * "please scale this to such and such" but rather
 * "the wxImage is already sized for backing scale such and such". )
 * Unfortunately, the constructor changes the size of wxBitmap too.
 * Thus We need to use unscaled size value for bitmaps that we use
 * to avoid scaled size of control items.
 * For this purpose control drawing methods and
 * control size calculation methods (virtual) are overridden.
