Query for semi-transparency support
Here's a warning, but it sounds like it's at a deep (C, presumably) level,
xfig()
grid::grid.rect(gp=gpar(fill="red", alpha=0.5))
Warning message:
In grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height,
resolveHJust(x$just, :
semi-transparency is not supported on this device: reported only once per page

In ?par there is the following line: ?"Semi-transparent colors are available for use on devices that support them." I'm looking for a way to query for that support on the current device. I'm pretty sure that this functionality exists at some level as I remember seeing warnings to this effect but my searches have come up empty. Is anyone familiar with a direct path to this information? Thank you, Jesse
