-/** Wserv access to render stage Text Cursor implementation.
-
-This interface allows delegation of Text Cursor drawing to the Render
-Stage.  It must not to be confused with Custom Text Cursor drawing;
-@see RWsSession::SetCustomTextCursor
-
-Historically, Text cursors have often been implemented using XOR
-drawing, because it is a cheap way to deliver a high-contrast cursor
-in certain system architectures where Operating System access to
-Graphics Device Memory is possible.
-
-XOR drawing can be problematic for some Render Stages.  This is because
-the XOR operation requires a read back followed by a write.  This would
-stall a graphics accelerator hardware implementation.
-
-In a render stage setting, the Text Cursor may not be the top-most
-window as a transition effect can slide a semi-transparent window over
-the top of the Text Cursor window.  This means the cursor cannot be XOR
-drawn last after all other windows; the read-back cost cannot be hidden
-at the end of drawing each frame.
-
-The Display Render Stage, responsible for interacting with hardware,
-can offer XOR drawing in some cases, for example Software Bit GDI,
-and not in others, for example OpenVG back-end hardware.
-
-This interface allows a render stage to implement Text Cursors
-appropriately given the Display Render Stage which is present.
-
-This interface uses the supplied Text Cursor Color as a hint only.
-TextCursor colors are better regarded as constrast level indicators
-where KRgbWhite means a high contrast text cursor, and KRgbBlack
-means an invisible text cursor.
-
-Suggested strategies:
-<ol>
-<li>
-XOR drawing is available.  Just XOR draw the cursor each time in
-the supplied color.  This corresponds to legacy non-Render Stage
-behaviour.
-</li>
-<li>
-No XOR drawing is available.  Draw a black box (solid or hollow
-as appropriate).  Ensure that the UI Toolkit which provides the
-platform's default text entry control has a compatible theme so
-that black is an appropriate high-contrast color.
-</li>
-</ol>
