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