Specifies the target texture. Must be GL_TEXTURE_1D or
GL_PROXY_TEXTURE_1D.
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_R3_G3_B2, 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. The height of the 1D texture image is 1.
Specifies the width of the border. Must be either 0 or 1.
Specifies the format of the pixel data. The following symbolic values
are accepted: GL_COLOR_INDEX, GL_RED, GL_GREEN, GL_BLUE,
GL_ALPHA, GL_RGB, GL_RGBA, GL_LUMINANCE, and
