(Set/GetEnableAntiAliasing, Set/GetEnableHiRes) and demo

|
|
SetBackgroundColour/SetForegroundColour on a PlotCanvas instance)
|

|
occur on access. This will postpone any IPP and / or CUPS warnings
|
|
which appear on stderr on some Linux systems until printing
|
|
functionality is actually used.

|
|
improvement though. Lines are much faster than markers, especially
|
|
filled markers. Stay away from circles and triangles unless you
|
|
only have a few thousand points.
