glTexSubImage1D
Notes
glTexSubImage1D is available only if the GL version is 1.1 or greater.
Texturing has no effect in color index mode.
The format GL_DEPTH_COMPONENT may only be used if the GL_EXT_shadow
extension is supported.
glPixelStore and glPixelTransfer modes affect texture images in exactly the way they
affect glDrawPixels.

GL_INVALID_VALUE may be generated if level is greater than log
is the returned value of GL_MAX_TEXTURE_SIZE.
GL_INVALID_VALUE is generated if xoffset < - b, or if (xoffset + width) > (w - b),
where w is the GL_TEXTURE_WIDTH, and b is the width of the
GL_TEXTURE_BORDER of the texture image being modified. Note that w includes
twice the border width.
GL_INVALID_VALUE is generated if width is less than 0.
