Changes required to convert MemoPad to a QVGA aware application.
Based on the PalmOS 4.0 SDK version, all changes are surrounded by:
/* TRG */
changes
/* end TRG */
to make them easier to find.  All code changes are within MemoMain.c

1. Resource changes.

  a.  Add QVGA IconsAdd IconID 2000 and 2001 which are 32x32 (1.5x icon view icon) and
      22x15 (1.5x list view icon).
  b.  Change ListView table number of rows to 25.
  c.  Add HandEra.r resource to indicate it is a Handera 330 aware application.
  d.  Fix typo in AlertID 2000, remove extra space before first period.

2.  Support the larger screen.  Switching to 1to1 mode (240x240) gives
    access to the additional fonts and allows supporting the minimized
    silk screen.  Note that if you have any bitmaps, you'll need to add
    1.5x versions at originalID + 0x1000 to your resources.

  a.  Add #include "vga.h" to the top.
  b.  Add a vgaExists global (Boolean).
  c.  Add a check for vga existence in StartApplication() and set the
      vgaExists global.
  d.  Add a call to VgaSetScreenMode() in StartApplication().
  e.  Add call to VgaFormModify() in EditViewHandleEvent and
      ListViewHandleEvent frmOpenEvent and frmGotoEvent cases.
  f.  Add VgaFormModify() to the modal forms in: DetailsInit(),
      DeleteRecord(), EditViewDeleteRecord(), and PreferencesInit().

3. Cleanup font issues.  The default font needs to be changed to the
   standard font instead of the smallest.  Also, calls to
   VgaTableUseBaseFont() need to be put in where the table is using
   small fonts.

  a.  ListViewHandleEvent() frmOpenCase, add VgaTableUseBaseFont(, !VgaIsVgaFont()).
  b.  SelectFont() add VgaTableUseBaseFont(, !VgaIsVgaFont()) if it is ListView.
  c.  MemoLoadPrefs() add VgaBaseToVgaFont() to get the correct default font.
  d.  ListViewDisplayMask() adjust for new lock bitmap size and use new bitmap
      when using a Vga font.

4. Support the virtual silk screen.
  
  a.  Add functions EditViewResizeForm() and ListViewResizeForm(),
      and the utility functions PrvMoveObject(), PrvResizeObject(),
      and PrvFrmGetGSI().
  b.  Call appropriate ResizeForm function from frmOpenEvent to
      handle the case where the app is launched with the silk minimized.
  c.  Add vgaChangedEvent to ListViewHandleEvent and EditViewHandleEvent
      and call appropriate ResizeForm().

5. Support one-hand operation.
  a.  Add handler for chrCarriageReturn and chrEscape to EditViewHandleEvent()
      which returns to the ListView.
  b.  Add handlers for chrCarriageReturn, vchrNextField, and vchrPrevField
      to ListViewHandleEvent().
  c.  Unselect item if category changes.
