/** InvertPrimitive2D class
|
|
|
|
This is a helper class which encapsulates geometry that should be
|
|
painted XOR, e.g. old cursor visualisations. It decomposes to
|
|
its content, so when not supporting it, the contained geometry
|
|
will be visualized normally.
|
|
Unfortunately this is still needed, but hard to support on various
|
|
systems. XOR painting needs read access to the target, so modern
|
|
graphic systems tend to not support it anymore.
