struct TTextCursor
/** Text cursor parameter information.

A text cursor is a rectangular area which can be set to flash. It is normally
only visible when the window group which owns it has the keyboard focus. This
structure is used to define the parameters of a text cursor, which can be
selected for use through the window group using RWindowGroup::SetTextCursor().

Custom (non-rectangular) text cursors are supported from v7.0s. They are added
to the window server using RWsSession::SetCustomTextCursor(), after which
they can be selected for use through the window group, in the same way as
standard rectangular cursors. They have a unique identifier, stored in the
iType member, which must be greater than ETypeLastBasic. Custom text cursors
are clipped to their iHeight and iWidth values. Their iColour member is not
used.
