/*
AvAxisVPS is a subclass of AvViewportSetter that expects to manage
two objects. The first is a viewport setter typically containing a
raster object. The second is an AvAxis that is meant to surround the
first.
When the axis is enabled, the size of the AVPS is increased to support
the space needed for the labels. The raster's vps is moved inward by
the margins.
Example:
AVPS
| |
| ----- Axis, ...
VPR
|
|- Raster
.- <possibly more>
AVPS Axis viewportSetter
VPR viewportSetter containing a raster and, perhaps, a contour.
It should be possible to replace the raster with something else, but
the size may have to be explicitly set and it hasn't been tried yet.
------------
| tm |
| ------- |
| | | |
|lm| ras |rm|
| | | |
| ------ |
| bm |
------------
Labels are drawn in the margins.
