/*****************************************************************************
Resource Workshop has extended the MS Dialog editor's custom control
API in three main areas:
1) More than 1 custom control can be placed in a single DLL
2) The "Info" data structure has been extended to allow custom controls
to be added to the RW toolbox
3) The style data structure has been extended to allo custom controls
access to the CTLDATA field. This field contains up to 255 bytes
of binary data. A pointer to this data is passed to the control
in the WM_CREATE message at runtime.
*****************************************************************************/

Two new fields have been added to the CTLTYPE data structure to
make the RWCTLTYPE structure:
hToolBit is a handle to a 24X24 bitmap which is added to the
RW toolbox. If this field is 0, no button will be added for this style,
and it will only be selectable via the Custom control dialog. This bitmap
is "owned" by RW, and will be freed by RW when the dialog editor is
unloaded.
hDropCurs is a handle to a cursor which is used by RW when a user
selects the control from the toolbox. If 0, a cross cursor will be used
