返回新的 QQuickRenderTarget referencing an D3D11 texture object specified by texture .
pixelSize specifies the size of the image, in pixels. Currently only 2D textures are supported.
sampleCount specific the number of samples. 0 or 1 means no multisampling, while a value like 4 or 8 states that the native object is a multisample texture.
注意： the resulting QQuickRenderTarget does not own any native resources, it merely contains references and the associated metadata of the size and sample count. It is the caller's responsibility to ensure that the native resource exists as long as necessary.

返回新的 QQuickRenderTarget referencing an OpenGL renderbuffer object specified by renderbufferId .
The renderbuffer will be used as the color attachment for the internal framebuffer object. This function is provided to allow targeting renderbuffers that are created by the application with some external buffer underneath, such as an EGLImageKHR. Once the application has called glEGLImageTargetRenderbufferStorageOES , the renderbuffer can be passed to this function.
pixelSize specifies the size of the image, in pixels.
sampleCount specific the number of samples. 0 or 1 means no multisampling, while a value like 4 or 8 states that the native object is a multisample renderbuffer.
注意： the resulting QQuickRenderTarget does not own any native resources, it merely contains references and the associated metadata of the size and sample count. It is the caller's responsibility to ensure that the native resource exists as long as necessary.

返回 true，若此 QQuickRenderTarget is default constructed, referencing no native objects.
返回 true 若 a and b refer to a different set of native objects, or the associated data (size, sample count) does not match.
返回 true 若 a and b refer to the same set of native objects and have matching associated data (size, sample count).
