Comment(by gisix):

 Intended workflow (Pseudocode):

 ----
 1) The user provides custom mapping information as a d.save output file
 "FOO" (raster,vector,annotations,lettering,whatever)

 2) The content of FOO is exported as the geotiff "BAZ" [conveniently
 provided via an extended r.out.file module..]

 3) BAZ can be used by other software (like GMT)


 ----

 Current ugly bash script. Works with GRASS 6.4.4. Code has not been
 implemented for GRASS 7.x

 ###########################################

 # Start dummy-monitor to recreate user-sided monitor content
 # TBD: Why does d.out.file not cooperate with a PNG monitor ?
 d.mon start=x7
 d.mon select=x7

 ###########################################
 # Execute user-provided monitor content in x7

 sh ./$GRASS_MONITOR_DSAVE_FILE

 ###########################################
 # Failsafe: Remove precautiously d.out.file output as the script doesn't
 allow --o overwrite.

 rm ${OUTPUT_FILE}

 ###########################################
 # Write out monitor content as Geotiff:

 d.out.file output=${OUTPUT_FILE} format=geotiff resolution=1
 size=$MONITOR_WIDTH,$MONITOR_HEIGHT

 ##########################################
 # Terminate monitor d.mon stop=x7
