/************************* CImageAttr dialog *******************************/
/*
There are a few things to note about the way this object/dialog functions.
It tries not to convert the currently displayed value unless it notices the
user has modified it. In all other cases, it works with PIXELS, the value
passed in. If the user modified the width or height, it does 1 conversion and
then works with pixels.
For the conversion to display the different unit values, it uses the saved
pixel value.
The reason for all of this is due to only n decimal place of accuracy in the
display
The member Vars m_lWidth and m_lHeight are in the current units (store in
the member variable m_eUnitsCurrent).
The member Vars m_lWidthPixels and m_lHeightPixels are always in Pixels and
these are what are used to convert for the display when changing the units.
