Version 1.6.5 or higher - only refactoring  (message cracker)

WM_SIZE for Histogram windows is replaced by message cracker macro & function

FIX IS NOT NEEDED:
The following bug is DOES NOT appear in TC (it exhibits only in my own ListerPluginTester):

In 32-bit version the header row  in a List Control does not appear if program starts with showing one of List View controls (but after resizing or switching to other tab and back or clicking on its area it appears)
Version 1.6.5 or higher - only refactoring  (message cracker)

WM_PAINT for Histogram windows is replaced by message cracker macro & function

Now all windows messages are handled by message cracker macros & functions
