The target of the operation, specified by <parameter>target</parameter> must be <constant>GL_RENDERBUFFER</constant>.

<parameter>internalformat</parameter> specifies the internal format to be used for the renderbuffer object's storage and

must be a color-renderable, depth-renderable, or stencil-renderable format.
|

<parameter>width</parameter> and <parameter>height</parameter> are the dimensions, in pixels, of the renderbuffer.

Both <parameter>width</parameter> and <parameter>height</parameter> must be less than or equal to the value of

<constant>GL_MAX_RENDERBUFFER_SIZE</constant>.
