FWIW, my GUI is not gis.m, nor is it related in any way to any other GRASS
GUIs, current or historical. It is an original product. As you might
guess, explaining the need for and the development of a separate GUI could
become a long story.
How long will the project continue to support 6.* versions?

Hi,
2011/4/13 <[email protected]>:
I'm aware that XDRIVER is antiquated piece of software that the project does
not intend to use for it's primary display or interactive tool. I have two
main questions (and maybe some to follow up):
Does the project intend to retain XDRIVER in the distribution?
Are there any plans to update or upgrade XDRIVER?
No, XDRIVER has been removed from trunk (GRASS 7) some months ago. In
other words GRASS 7 drops Xmonitors and all related d.* modules
(d.zoom, d.pan, etc).
As a bit of background, I use a Tcl/TK GUI for GRASS that I have been
developing incrementally since roughly 1997, so not only is the GUI fairly
well-developed but I'm pretty accustomed to it and I intend to keep it. The
GUI uses XDRIVER as it's primary display and interactive tool and ps.map for
high quality output.
You mean `d.m` I guess. In GRASS 7 TCL/TK GUI has been also dropped.
There is only new wxGUI available. There are no plans to recover
TCL/TK GUI development, AFAIK.
I recently started developing a module that would let me interactively
construct map annotations using points, lines, arrows, rectangles,
polylines, polygons and text. When I started constructing the text
capability I found that R_get_text_box() produced grossly incorrect results.
That compounded the problem with low quality of the screen fonts -- even
using FreeType2.
I remedied the problem by adding libXft to XDRIVER. That gave me
high-quality, antialiased, client-side fonts and replaced all of the
font-handling and rendering capabilities currently in GRASS. And it
enormously simplified the code. And R_get_text_box() produces the right
result.
Adding Xft changed the behavior of some text and font modules: label
placement in d.vect is great, but d.font didn't work and d.paint.labels
references labels incorrectly. There are probably other changes that I'll
find later.
I am not expert here, so I am leaving comments to others. Anyway,
display architecture in GRASS 7 is primary based on Cairo library. New
development goes in that direction.
