// D3DXSPRITE flags:
// -----------------
// D3DXSPRITE_DONOTSAVESTATE
//   Specifies device state is not to be saved and restored in Begin/End.
// D3DXSPRITE_DONOTMODIFY_RENDERSTATE
//   Specifies device render state is not to be changed in Begin.  The device
//   is assumed to be in a valid state to draw vertices containing POSITION0, 
//   TEXCOORD0, and COLOR0 data.
// D3DXSPRITE_OBJECTSPACE
//   The WORLD, VIEW, and PROJECTION transforms are NOT modified.  The 
//   transforms currently set to the device are used to transform the sprites 
//   when the batch is drawn (at Flush or End).  If this is not specified, 
//   WORLD, VIEW, and PROJECTION transforms are modified so that sprites are 
//   drawn in screenspace coordinates.
// D3DXSPRITE_BILLBOARD
//   Rotates each sprite about its center so that it is facing the viewer.
// D3DXSPRITE_ALPHABLEND
//   Enables ALPHABLEND(SRCALPHA, INVSRCALPHA) and ALPHATEST(alpha > 0).
//   ID3DXFont expects this to be set when drawing text.
// D3DXSPRITE_SORT_TEXTURE
//   Sprites are sorted by texture prior to drawing.  This is recommended when
//   drawing non-overlapping sprites of uniform depth.  For example, drawing
//   screen-aligned text with ID3DXFont.
// D3DXSPRITE_SORT_DEPTH_FRONTTOBACK
//   Sprites are sorted by depth front-to-back prior to drawing.  This is 
//   recommended when drawing opaque sprites of varying depths.
// D3DXSPRITE_SORT_DEPTH_BACKTOFRONT
//   Sprites are sorted by depth back-to-front prior to drawing.  This is 
//   recommended when drawing transparent sprites of varying depths.
// D3DXSPRITE_DO_NOT_ADDREF_TEXTURE
//   Disables calling AddRef() on every draw, and Release() on Flush() for
//   better performance.
