103 * SM_CYHSCROLL x+1 x Fixed May 24, 1999 - Ronald B. Cemer
104 * SM_CXDLGFRAME x-1 x Already fixed
105 * SM_CYDLGFRAME x-1 x Already fixed
106 * SM_CYCAPTION x+1 x Fixed May 24, 1999 - Ronald B. Cemer
107 * SM_CYMENU x-1 x Already fixed
108 * SM_CYFULLSCREEN x-1 x
109 * SM_CXFRAME Fixed July 6, 2001 - Bill Medland
111 * (collides with TWEAK_WineLook sometimes,
112 * so changing anything might be difficult)
114 * Starting at Win95 there are now a large number or Registry entries in the
115 * [WindowMetrics] section that are probably relevant here.
