89 * SM_CXVSCROLL x+1 x Fixed May 24, 1999 - Ronald B. Cemer
90 * SM_CYHSCROLL x+1 x Fixed May 24, 1999 - Ronald B. Cemer
91 * SM_CXDLGFRAME x-1 x Already fixed
92 * SM_CYDLGFRAME x-1 x Already fixed
93 * SM_CYCAPTION x+1 x Fixed May 24, 1999 - Ronald B. Cemer
94 * SM_CYMENU x-1 x Already fixed
95 * SM_CYFULLSCREEN x-1 x
96 * SM_CXFRAME Fixed July 6, 2001 - Bill Medland
98 * (collides with TWEAK_WineLook sometimes,
99 * so changing anything might be difficult)
101 * Starting at Win95 there are now a large number or Registry entries in the
102 * [WindowMetrics] section that are probably relevant here.
