SysImgList Class Reference

#include <uLib/SysImgList.h>

Detailed Description

Access the system image lists the hard-core way..

Note: Direct use of ImageList_Draw() results in superior drawing speed,
far outperforming both ImageList_GetIcon()/DrawIconEx() and IImageList::Draw().

If you need sizes apart from 16 and 32, you're confined to IImageList,
so say goodbye to decent performace, since you won't get it's HIMAGELIST.
