[PATCH 0/4] MR5639: comctl32/syslink: Don't delete font when destroying the control.

[Zhiyi Zhang (＠zhiyi)]

The font set by WM_SETFONT is not owned by syslink so it shouldn't be deleted when handling
WM_DESTROY for the control.

Fix Toad for Oracle text gets reset to the system font after installing Team Coding. The application
creates a font and set it to a syslink. Then after the syslink destroys itself, the font becomes
invalid so other controls using the font end up falling back to the system font.
