/*
* Clip value is ignored in D3D SurfaceToSw blit.
* Root Cause: The native interfaces to D3D use StretchRect API followed
* by custom copy of pixels from Surface to Sysmem. As a result, clipping
* in D3DSurfaceToSw works 'only' for Rect clips, provided, proper srcX,
* srcY, dstX, dstY, width and height are passed to native interfaces.
* Non rect clips (For example: Shape clips) are ignored completely.
*
* Solution: There are three solutions possible to fix this issue.
* 1. Convert the entire Surface to Sysmem and perform regular Blit.
* An optimized version of this is to take up the conversion only
* when Shape clips are needed. Existing native interface will suffice
* for supporting Rect clips.
* 2. With help of existing classes we could perform SwToSurface,
* SurfaceToSurface (implements clip) and SurfaceToSw (complete copy)
* in order.
* 3. Modify the native D3D interface to accept clip and perform same logic
* as the second approach but at native side.
*
* Upon multiple experiments, the first approach has been found to be
* faster than the others as it deploys 1-draw/copy operation for rect clip
* and 2-draw/copy operations for shape clip compared to 3-draws/copy
* operations deployed by the remaining approaches.
*
* complexClipBlit method helps to convert or copy the contents from
* D3DSurface onto Sysmem and perform a regular Blit with the clip
* information as required. This method is used when non-rectangular
* clip is needed.

/*
* The following classes prohibit copying D3DSurfaces to the screen
* (the D3D->sysmem->GDI path is known to be very very slow).
*
* Note: we used to disable hw acceleration for the surafce manager associated
* with the source surface in these loops but it proved to be too cautious.
*
* In most cases d3d->screen copy happens only during some transitional
* period where the accelerated destination surface is being recreated or
* restored (for example, when Swing's backbuffer VI is copied to the screen
* but the D3DScreenSurfaceManager couldn't restore its surface).
*
* An exception is if for some reason we could not enable accelerated on-screen
* rendering for this window for some permanent reason (like window being too
* small, or a present BufferStrategy).
*
* This meant that we'd disable hw acceleration after the first failure
* completely (at least until the src image is recreated which in case of
* Swing back-buffer happens only after resize).
*
* Now we delegate to the VISM to figure out if the acceleration needs to
* be disabled or if we can wait for a while until the onscreen accelerated
* can resume (by marking the source surface lost and making sure the
* VISM has a chance to use the backup surface).
