  67. Reasons for patches:
  69. Blitting at interrupt time and avoiding menus accounts for the
  70. following trap patches:
  71. - CopyBits (to see where the menus are)
  72. - MenuSelect (to see when the menu is down)
  73. - PopupMenuSelect
  75. Seeing when we switch out of the application accounts for the
  76. following trap patch:
  77. - WaitNextEvent (to watch for osEvt switching in/out)
  79. Ensuring that the current visRgn is what we're using
  80. for the visRgn -- ie, things where we wait for a system-time
  81. call to update our version of the visRgn...
  82. - MoveWindow
  83. - CloseWindow
  84. - SelectWindow
  85. - PaintBehind (like when the app quits)
  86. - BringToFront (deprecated because SelectWindow is better but
  87.   apparently the fine folks at Netscape didn't hear that.)
  88. - SendBehind (also used by Netscape and apparently nobody else)
  90. Note: I think that with the PaintBehind trap being patched, it
  91. makes the CloseWindow patch redundant. At least until code
  92. is added that blits over the last "XORed" part of the dragged
  93. window frame.
  95. Note: Menus popped up from the Control Strip are being blasted
  96. over. ControlStripDispatch is a likely candidate to patch to
  97. turn on the theMenuIsDown boolean, but I'm gonna
  98. procrastinate on that.
