[gradsusr] Why have widgets been disabled in v2.1.a1

[Jennifer Adams]

Hi, Tim -- 
In future releases, you will be able to choose at run time which graphics rendering engine you wish to use: 
(a) Cairo, which handles the drawing in the X11 window and all hardcopy outputs (images and vector graphics)
(b) Classic, which has direct X11 calls and supports widgets and uses the GD library to create image output. 

The widgets will never work with the Cairo graphics interface, they will only work with the classic X11 interface. Vector graphics hardcopy output (such as postscript) will only be available with Cairo, or with older versions of GrADS.  Fonts, anti-aliasing, and transparent colors are only available with Cairo and will never be a part of the classic interface. So, your interactive interface will be fine as long as you can make do without fancy pants graphics.
