I slightly updated your fix to return a multi-resolution image with base
icon size when icon size is greater than the real icon size. This allows
to draw a high-resolution icon to the same bounds on JOptionPane.
I have not found the solution for the native toolbar icons yet. An icon
with IDB_VIEW_SMALL_COLOR has size 16x16 on my Windows 8.1. The
GetSystemMetrics(SM_CXSMICON) returns 32. It is a question for me should
IDB_VIEW_SMALL_COLOR icon has the same size as the
An icon with IDB_VIEW_LARGE_COLOR returns also icon with size 16x16 and
the returned image contains only one quarter of the original picture.
I left the code for the toolbar icons as it was before so it uses low
resolution IDB_VIEW_SMALL_COLOR icons.
I think it can be fixed as a separated issue.
