NAME

       glTexImage2DMultisample - establish the data storage, format, dimensions, and number of samples of a
       multisample texture's image

C SPECIFICATION

       void glTexImage2DMultisample(GLenum target, GLsizei samples, GLenum internalformat, GLsizei width,
                                    GLsizei height, GLboolean fixedsamplelocations);

PARAMETERS

       target
           Specifies the target of the operation.  target must be GL_TEXTURE_2D_MULTISAMPLE or
           GL_PROXY_TEXTURE_2D_MULTISAMPLE.

       samples
           The number of samples in the multisample texture's image.

       internalformat
           The internal format to be used to store the multisample texture's image.  internalformat must specify
           a color-renderable, depth-renderable, or stencil-renderable format.

       width
           The width of the multisample texture's image, in texels.

       height
           The height of the multisample texture's image, in texels.

       fixedsamplelocations
           Specifies whether the image will use identical sample locations and the same number of samples for
           all texels in the image, and the sample locations will not depend on the internal format or size of
           the image.

DESCRIPTION

       glTexImage2DMultisample establishes the data storage, format, dimensions and number of samples of a
       multisample texture's image.

       target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE.  width and height are the
       dimensions in texels of the texture, and must be in the range zero to the value of GL_MAX_TEXTURE_SIZE
       minus one.  samples specifies the number of samples in the image and must be in the range zero to the
       value of GL_MAX_SAMPLES minus one.

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

       If fixedsamplelocations is GL_TRUE, the image will use identical sample locations and the same number of
       samples for all texels in the image, and the sample locations will not depend on the internal format or
       size of the image.

       When a multisample texture is accessed in a shader, the access takes one vector of integers describing
       which texel to fetch and an integer corresponding to the sample numbers describing which sample within
       the texel to fetch. No standard sampling instructions are allowed on the multisample texture targets.

NOTES

       glTexImage2DMultisample is available only if the GL version is 3.2 or greater.

ERRORS

       GL_INVALID_OPERATION is generated if internalformat is a depth- or stencil-renderable format and samples
       is greater than the value of GL_MAX_DEPTH_TEXTURE_SAMPLES.

       GL_INVALID_OPERATION is generated if internalformat is a color-renderable format and samples is greater
       than the value of GL_MAX_COLOR_TEXTURE_SAMPLES.

       GL_INVALID_OPERATION is generated if internalformat is a signed or unsigned integer format and samples is
       greater than the value of GL_MAX_INTEGER_SAMPLES.

       GL_INVALID_VALUE is generated if either width or height negative or is greater than GL_MAX_TEXTURE_SIZE.

       GL_INVALID_VALUE is generated if samples is greater than GL_MAX_SAMPLES.
