/**
 * Creates an FBO, allocating the underlying FrameBuffer and the desired attachments on the GPU.
 *
 * Also checks the resulting FBO for completeness and logs errors and their error codes as necessary.
 * Callers must check the returned FBO's status (see getStatus()). Only FBO with a Status.COMPLETE should be used.
 *
 * In what follows, the GL constants between parenthesis represent the (internal format, data type, filtering type) of a buffer.
 *
 * An FBO of Type.DEFAULT will have a 32 bit color buffer attached to it. (GL_RGBA, GL11.GL_UNSIGNED_BYTE, GL_LINEAR)
 * An FBO of Type.HDR will have a 64 bit color buffer attached to it. (GL_RGBA, GL_HALF_FLOAT_ARB, GL_LINEAR)
 * An FBO of Type.NO_COLOR will have -no- color buffer attached to it.
 *
 * If the creation process is successful (Status.COMPLETE) GPU memory has been allocated for the FrameBuffer and
 * its attachments. However, the content of the attachments is undefined.
 *
 * @param urn An identification string. It is currently used only to log creation errors and is not stored in the FBO.
 * @param dimensions A Dimensions object wrapping width and height of the FBO.
 * @param type Can be Type.DEFAULT, Type.HDR or Type.NO_COLOR
 * @param useDepthBuffer If true the FBO will have a 24 bit depth buffer attached to it. (GL_DEPTH_COMPONENT24, GL_UNSIGNED_INT, GL_NEAREST)
 * @param useNormalBuffer If true the FBO will have a 32 bit normals buffer attached to it. (GL_RGBA, GL_UNSIGNED_BYTE, GL_LINEAR)
 * @param useLightBuffer If true the FBO will have 32/64 bit light buffer attached to it, depending if Type is DEFAULT/HDR.
 *                       (GL_RGBA/GL_RGBA16F_ARB, GL_UNSIGNED_BYTE/GL_HALF_FLOAT_ARB, GL_LINEAR)
 * @param useStencilBuffer If true the depth buffer will also have an 8 bit Stencil buffer associated with it.
 *                         (GL_DEPTH24_STENCIL8_EXT, GL_UNSIGNED_INT_24_8_EXT, GL_NEAREST)
