.Xresources settings to make Motif look a bit less archaic for DDD

.Xresources

! ---=== Experiment with making Motif less ugly for DDD ===---
! (DDD ignores generically-set Motif properties so we must do this)
! TODO (if possible):
!  - Hide text cursors in unfocused fields
!  - Convert on-hover effect from shadow to background color or border
!  - Pick better fonts and check which package provides them

! Use the lighter background grey from the Lubuntu GTK+ theme
! (Still a cool grey. Eyedropper the Clearlooks warm grey if necessary.)
Ddd*background: #e0e0e0

! These had no effect on my system but, from what I read, they help on
! some systems.
