Detailed Description

A deferred render object which allocates a multisampling depth and color texture which can be used in an implementation of renderFramebuffer() as textures:

RefPtr<GLProgram> myProgram;
        myProgram->setUniformTexture("SceneColor", *myColorTexture);
        myProgram->setUniformTexture("SceneDepth", *myDepthTexture);

Doing such requires samplers defined in the GLSL shader code in the following form:

uniform sampler2DMS SceneColor;
uniform sampler2DMS SceneDepth;

The data in these textures is then accessible in fragment shader code via

ivec2   P = ivec2( gl_FragCoord.xy);
 
vec4    Color = texelFetch(SceneColor, P, 0 );
float   Depth = texelFetch(SceneDepth, P, 0 ).r;

It is recommended to be used as base class for multisampling deferred render objects derived from class MSDeferredRenderObject.
