Adds a
limits_from_pvproperty to the image widget that sets the axis min/max to reflect the pixel coordinates with origin in the upper left corner.With PVA, the image size is taken from the PV. With Channel Access, the
data_widthanddata_heightproperties are used.To remain compatible with existing displays, the default is
limits_from_pv=false.As before, that allows setting the
x_axis.minimum,y_axis.maximumetc. either manually or from scripts and rules.For scripts or rules that want to use the pixel dimensions, a new pair of
imageWidth(VImage)andimageHeight(VImage)formula functions have been added.
