Specifies the target texture. Must be GL_TEXTURE_2D or
GL_PROXY_TEXTURE_2D.
Specifies the level-of-detail number. Level 0 is the base image level.
Level n is the nth mipmap reduction image.
Specifies the number of color components in the texture. Must be 1, 2,
3, or 4, or one of the following symbolic constants: GL_ALPHA,
GL_ALPHA4, GL_ALPHA8, GL_ALPHA12, GL_ALPHA16,
GL_LUMINANCE, GL_LUMINANCE4, GL_LUMINANCE8,
GL_LUMINANCE12, GL_LUMINANCE16,
GL_LUMINANCE_ALPHA, GL_LUMINANCE4_ALPHA4,
GL_LUMINANCE6_ALPHA2, GL_LUMINANCE8_ALPHA8,
GL_LUMINANCE12_ALPHA4, GL_LUMINANCE12_ALPHA12,
GL_LUMINANCE16_ALPHA16, GL_INTENSITY, GL_INTENSITY4,
GL_INTENSITY8, GL_INTENSITY12, GL_INTENSITY16,
GL_R3_G3_B2, GL_RGB, GL_RGB4, GL_RGB5, GL_RGB8,
GL_RGB10, GL_RGB12, GL_RGB16, GL_RGBA, GL_RGBA2,
GL_RGBA4, GL_RGB5_A1, GL_RGBA8, GL_RGB10_A2,
GL_RGBA12, or GL_RGBA16. Additionally, if the extension
GL_EXT_shadow is supported, may be one of the symbolic constants
GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT16_EXT,
GL_DEPTH_COMPONENT24_EXT, or
GL_DEPTH_COMPONENT32_EXT.
Specifies the width of the texture image. Must be 2
some integer n. All implementations support texture images that are
at least 64 texels wide.
Specifies the height of the texture image. Must be 2
some integer m. All implementations support texture images that are
at least 64 texels high.
Specifies the width of the border. Must be either 0 or 1.
