- A link entry can now contain additional text (for user feedback) and width.
Parameters for a link entry can come in any order.
- Links can be 1 dimensional (like lines) or 2 dimensional (like regions).
- Link entities now include all entity types:
points, lines, polylines, circles, arcs, rectangles, bezier curves, and text.
- Text now uses a system courier-like font as a default for displaying text.
- Text can be specified with a suggested width.
Therefore link and notification information are now specified with 'Name' instead of 'Text'.
- An optimization flag can be specified which indicates that entities within a layer
can be rearranged while displaying for optimization.
Entities can still be displayed in the order they occur in the file.
- Scale factor and base point can be included in the file.
This can be used to recreate the original coordinate system of the image.
This information is not used for display.

bits instead of just the most significant bit.
