Move the nine #undef's common to all qt_*.cpp sources into qt_pre.h.
Make "hack.h" usage consistent; always enclose withing 'extern "C {'
and '}' even though only some of the sources care.
In case you haven't seen it, the Qt screen layout is (a bigger
instance of):
+--------------------+------+--------------------------------+
| messages |invent| status |
| |subset| |
| | | |
| | | |
+------------------------------------------------------------+
| map |
| |
...
| |
+------------------------------------------------------------+
where some status fields include an icon and the inventory subset is
a miniature map showing a paper doll-style display of object tiles
for worn and wielded items. The two separating lines in the top half
can be dragged to resize the three windows there. The default message
window width to too small to see full text of some messages but can
be scrolled left and right. The window for the equipped subset of
inventory is unconditionally present; 'perm_invent' is a no-op.
Paper doll inventory layout (view with fixed-width font...):
Old New two-hand dual-wield
x H b x H b x H b . H b
S " w S " w W " W X " w
G C G G C q G C q G C q
= A = = A = = A = = A =
. U . l U L l U L l U L
. F . . F . . F . . F .
Legend:
'.' = blank, b = blindfold, '"' = amulet, '=' = left and right rings,
w/W = primary weapon, x/X = alternate/secondary weapon, q = quiver,
H = helmet, S = shield, G = gloves, C = cloak, A = suit, U = shirt,
F = boots, l = leash, L = active light source (lamp/candle/Sunsword).
Slots which don't have something equipped are shown blank.
'q' was missing; 'G' used to be shown on both sides. 'l' and 'L' are
new; for either, it picks the first one in inventory that's in active
use. The 'S' and 'x' slots vary depending upon weapon situation
since wearing a shield, wielding a two-handed weapon, and engaging in
two-weapon combat are all mutually exclusive.
