    <remarks>
      <para>
        <see cref="T:Urho.Scene" /> rendering and any post-processing on a Viewport is defined by its RenderPath object, which can either be read from an XML file or be created programmatically.</para>
      <para>The render path consists of rendertarget definitions and commands. The commands are executed in order to yield the rendering result. Each command outputs either to the destination rendertarget &amp; viewport (default if output definition is omitted), or one of the named rendertargets. MRT output is also possible. If the rendertarget is a cube map,</para>
      <para>the face to render to (0-5) can also be specified.</para>
      <para>A rendertarget's size can be either absolute or multiply or divide the destination viewport size. The multiplier or divisor does not need to be an integer number. Furthermore, a rendertarget can be declared "persistent" so that it will not be mixed with other rendertargets of the same size and format, and its contents can be assumed to be available also on subsequent frames.</para>
      <para>Note that if you already have created a named rendertarget texture in code and have stored it into the resource cache by using <see cref="M:Urho.ResourceCache.AddManualResource" /> you can use it directly as an output (by referring to its name) without requiring a rendertarget definition for it.</para>
      <para>
      </para>
      <para>The available commands are:</para>
      <list type="bullet">
        <item>
          <term>clear: Clear any of color, depth and stencil. Color clear can optionally use the fog color from the Zone visible at the far clip distance.</term>
        </item>
        <item>
          <term>scenepass: Render scene objects whose <see cref="T:Urho.Material" /> contains the specified pass. Will either be front-to-back ordered with state sorting, or back-to-front ordered with no state sorting. For deferred rendering, object lightmasks can be optionally marked to the stencil buffer. Vertex lights can optionally be handled during a pass, if it has the necessary shader combinations. Textures global to the pass can be bound to free texture units; these can either be the viewport, a named rendertarget, or a texture resource identified with its pathname.</term>
        </item>
        <item>
          <term>quad: Render a viewport-sized quad using the specified shaders and compilation defines. Textures can be bound and additionally shader parameters and the blend mode (default=replace) can be specified.</term>
        </item>
        <item>
          <term>forwardlights: Render per-pixel forward lighting for opaque objects with the specified pass name. Shadow maps are also rendered as necessary.</term>
        </item>
        <item>
          <term>lightvolumes: Render deferred light volumes using the specified shaders. G-buffer textures can be bound as necessary.</term>
        </item>
        <item>
          <term>renderui: Render the UI into the output rendertarget. Using this will cause the default %UI render to the backbuffer to be skipped.</term>
        </item>
      </list>
      <para>A render path can be loaded from a main XML file by calling <see cref="M:Urho.RenderPath.Load" />, after which other XML files (for example one for each post-processing effect) can be appended to it by calling <see cref="M:Urho.RenderPath.Append" />. Rendertargets and commands can be enabled or disabled by calling <see cref="M:Urho.RenderPath.SetEnabled" /> to switch eg. a post-processing effect on or off. To aid in this, both can be identified by tag names, for example the bloom effect uses the tag "Bloom" for all of its rendertargets and commands.</para>
      <para>It is legal to both write to the destination viewport and sample from it during the same command: pingpong copies of its contents will be made automatically. If the viewport has hardware multisampling on, the multisampled backbuffer will be resolved to a texture before sampling it.</para>

        <h2>Depth-stencil handling and reading scene depth</h2>
      </format>
      <para>

	  Normally needed depth-stencil surfaces are automatically
	  allocated when the render path is executed.
	</para>
      <para>

	  The special "lineardepth" (synonym "depth") format is
	  intended for storing scene depth in deferred rendering. It
	  is not an actual hardware depth-stencil texture, but a
	  32-bit single channel (R) float rendertarget. (On OpenGL2
	  it's RGBA instead, due to the limitation of all color
	  buffers having to be the same format. The shader include
	  file Samplers.glsl in bin/CoreData/Shaders/GLSL provides
	  functions to encode and decode linear depth to RGB.)
	</para>
      <para>

	  Writing depth manually to a rendertarget, while using a
	  non-readable depth-stencil surface ensures best
	  compatibility and prevents any conflicts from using both
	  depth test and manual depth sampling at the same time.
	</para>
      <para>

	  There is also a possibility to define a readable hardware
	  depth texture, and instruct the render path to use it
	  instead. Availability for this must first be checked with
	  the function GetReadableDepthSupport(). On Direct3D9 this
	  will use the INTZ "hack" format. To define a readable
	  depth-stencil texture, use the format "readabledepth"
	  (synonym "hwdepth") and set it as the depth-stencil by using
	  the "depthstencil" attribute in render path commands. Note
	  that you must set it in every command where you want to use
	  it, otherwise an automatically allocated depth-stencil will
	  be used. Note also that the existence of a stencil channel
	  is not guaranteed, so stencil masking optimizations for
	  lights normally used by the Renderer and View classes will be
	  disabled.
	</para>
      <para>

	  In the special case of a depth-only rendering pass you can
	  set the readable depth texture directly as the "output" and
	  don't need to specify the "depthstencil" attribute at all.
	</para>
      <para>

	  After the readable depth texture has been filled, it can be
	  bound to a texture unit in any subsequent commands. Pixel
	  shaders should use the ReconstructDepth() helper function to
	  reconstruct a linear depth value between 0-1 from the
	  nonlinear hardware depth value. When the readable depth
	  texture is bound for sampling, depth write is automatically
	  disabled, as both modifying and sampling the depth would be
	  undefined.
	</para>
      <para>

	  An example render path for readable hardware depth exists in
	  bin/CoreData/RenderPaths/ForwardHWDepth.xml:
	</para>
      <code lang="XML"><![CDATA[

    </command>
    <command type="scenepass" pass="alpha" vertexlights="true" sort="backtofront" metadata="alpha" depthstencil="depth"  />
    <command type="scenepass" pass="postalpha" sort="backtofront" depthstencil="depth" />
</renderpath>
]]></code>
      <para>

	The render path starts by allocating a readable depth-stencil
	texture the same size as the destination viewport, clearing
	its depth, then rendering a depth-only pass to it. Next the
	destination color rendertarget is cleared normally, while the
	readable depth texture is used as the depth-stencil for that
	and all subsequent commands. Any command after the depth
	render pass could now bind the depth texture to an unit for
	sampling, for example for smooth particle or SSAO effects.

      </para>
      <para>

	The ForwardDepth.xml render path does the same, but using a
	linear depth rendertarget instead of a hardware depth
	texture. The advantage is better compatibility (guaranteed to
	work without checking <see cref="P:Urho.Graphics.ReadableDepthSupport" />) but it has
	worse performance as it will fill the hardware depth-stencil
	twice.
      </para>

        <h2>Special Considerations for Forward Lighting</h2>
      </format>
      <para>

	  Otherwise fully customized scene render passes can be
	  specified, but there are a few things to remember related to
	  forward lighting:
	</para>
      <para>

	  The opaque base pass must be tagged with metadata
	"base". When forward lighting logic does the lit base pass
	optimization, it will search for a pass with the word "lit"
	prepended, ie. if your custom opaque base pass is called
	"custombase", the corresponding lit base pass would be
	"litcustombase".
      </para>
      <para>

	The transparent base pass must be tagged with metadata
	"alpha". For lit transparent objects, the forward lighting
	logic will look for a pass with the word "lit" prepended,
	ie. if the custom alpha base pass is called "customalpha", the
	corresponding lit pass is "litcustomalpha". The lit drawcalls
	will be interleaved with the transparent base pass, and the
	scenepass command should have back-to-front sorting enabled.
      </para>
      <para>

	If forward and deferred lighting are mixed, the G-buffer
	writing pass must be tagged with metadata "gbuffer" to prevent
	geometry being double-lit also with forward lights.
      </para>
      <para>

	Remember to mark the lighting mode (per-vertex / per-pixel)
	into the techniques which define custom passes, as the lighting
	mode can be guessed automatically only for the known default
	passes.
      </para>
      <para>
	The forwardlights command can optionally disable the
	lit base pass optimization without having to touch the material
	tech iques, if a separate opaque ambient-only base pass is needed. B  default the optimization is enabled.
      </para>
      <format type="text/html">
        <h2>Special Considerations for Post-Processing Effects </h2>
      </format>
      <para>

	Post-processing effects are usually implemented by using the
	quad command. When using intermediate rendertargets that are
	of different size than the viewport rendertarget, it is
	necessary in shaders to reference their (inverse) size and the
	half-pixel offset for Direct3D9. These shader uniforms are
	automatically generated for named rendertargets. For an
	example look at the bloom postprocess shaders: the
	rendertarget called HBlur will define the shader uniforms
	cHBlurInvSize and cHBlurOffsets (both Vector2.)
      </para>
      <para>

	In OpenGL post-processing shaders it is important to
	distinguish between sampling a rendertarget texture and a
	regular texture resource, because intermediate rendertargets
	(such as the G-buffer) may be vertically inverted. Use the
	GetScreenPos() or GetQuadTexCoord() functions to get
	rendertarget UV coordinates from the clip coordinates; this
	takes flipping into account automatically. For sampling a
	regular texture, use GetQuadTexCoordNoFlip() function, which
	requires world coordinates instead of clip coordinates.
