Program readability improved. No behavior changes.
Changes:
- Added/edited documenting comments.
- Fixed wrong parameter name: renamed ignoreSelectedBox to includeSelectedBox (in Page.Overlaps())
- Disabled unused method (Page.PartCount).
- Removed unnecessary 'ref' keyword (in 'ref parts' parameter of the various 'AppendParts' methods).
- Avoid similar names to different objects:
- Renamed the (private) 'box' to '_mesh' in ClippingD3D.
- Renamed the (private) 'lines' to '_clippings' in PlayerViewD3D.

Experiment for vision quality. The changes of jed's experiment that improved the quality.
- In ClippingD3D.Get():
- Changed the clipping width and height to '0' (= 'from input'; was fixed 2048). This adapts to the input resolution (probably).
- 'Filter' was already changed in R114 from 'Linear' to 'Point' in ClippingD3D.Get(). Not sure if this had influence.
- In PlayerViewD3D.CreateDevice():
- Added specifying Backbuffer width and height explicitly. This adapts to the output resolution (probably).
