1. This is The Button component (really Button, as it's based on TButton component)
   It provide the hext Main functions:
        13 default forms + User defined form;
        7 Styles of Button Border;
        3 Styles of gradient fill;
          Gradient Bitmap allowed;
        3 Styles of Caption;
        Show/not show focus region, allow custom painting;
        The Button,Caption and Gradient Could be turned at any angle, (Also with User Defined form)
        Real Time Light/Shadow Calculating
        3 Types of Animation (On Button Enter,Exit and Press)
        The Button Point of rotation can be selected
        Button Could Rotated at real Time even in Design Mode (Not using Timer)
        All Parts of Button could be placed at any part of Button.
        All Forms of Button (include User) could be freely resized undependly on X and Y axe
  RgnEditor is The Editor of Regions (Button Forms).
  It Provide the next main Function:
        Selection The region at any kind of Bitmap
        Selection provided  as at Fore ground Color as at Back Ground Color
        You Can Use The not accurate on Colors Bitmaps to Choose Region (At Example Scanned Images)
        This is also Example of IAeverButton using.
  RotateRgn1 is Unit for back design of Regions from Microsoft inner presentation(couple of Rectangles)
  to PolyPolyline representation (With automatically calculation of multiplicity) and the border
  calculation.

3. RGNeditor is Region Editor that help you to construct User region from it's image on Bitmap
  So
  3.1. Paint The Image of Region on Bitmap (at example Scan,Paint manually and so on) and save it as BMP file.
  3.2. Load Bitmap at RGNEditor(You can SWitch on/off the auto RGN calculating in real time(Realized as parallel process))
  3.3. Select The Fore or Back color (Press the corresponding Button and select color from image)
  3.4. If more wastes then need on region You could remove it By selection of Smooth at up of Editor
  3.5. By Accuracy switch you can increase the colors regions (so All Colors near Back Color, at example, will count as Back Color)
  3.6. Press Ok button
  Please do not foget to select bkUser Type!

4. RotateRgn1 is unit with functions of back design of inner HRGN presentation to PolyPolynom kind.
 
Function                     Action

RotateRegion                 RotateRgn at defined point to angle
RecreateRgn                  Get Rgh: HRGN from PolyPoly presentation
PolyRotate                   Rotate PolyPoly at defined Point to angle
GetInner                     Shift Even Polys from PolyPoly at defined number of points inner and 
                             Odd polys Outer(all actions separatly could be denied)
GetLDppoly                   Calculate   the Light and Shadow regions between two PolyPolyes
RgnToPoly                    Get PolyPoly from region
SimplifyPolys                Simplify Polypoly (remove repeated points and points at one line)
