WD17 project based on GDImage 7.00 64-bit.

Its purpose is to display large architecture or road map images, to be illustrated with icon markers, like in "Google map".

Four distinct GDImage controls are used altogether.

1 - On top, an horizontal contact sheet with thumbnail preview, to select a specific map project to work with.
2 - In the center, the main ZOOM control, that is the work place.
3 - On the right side, a vertical contact sheet with the icon markers available, you can move them by drag and drop onto the main control.
4 - A floating window with a thumbnail of the whole map, and a slider to ajust the zoom ratio. The red border drawn around the rectangular section delimits the main control working section. You can drag it to move the working section rather than using the main scrollbars.

Properties :
- GDImage 7.00 64-bit (DWM composition + GPU accelerated mode + OpenGL extension, and 3D graph primitives)
- Icon drag & drop directly onto the GDImage container.
- Text annotation (right click on the background to open the contextual menu).
- Cut and paste between GDImage project or external applications.
- Tooltip label editing.
- Remember last open project.
- Multiple state sprite/icon marker (moving from one frame to another, from the contextual popup menu).
- Each sprite/icon can be flatten to the background.
- Memory optimisation (a specific icon marker is loaded only once in memory).
- Use of thumbnail cache to speed up the creation of the contact sheet even with large image.
- Main control image paning, from the small red rectangle shown in the thumbnail preview, or by dragging the image background, just like using the scrollbars.
- Move the window around, from the bottom task bar, that is a replacement for the standard caption.
- The open folder icon show/hide the contact sheet to select a new project.
