Specifies which texture unit to make active. The number
of texture units is implementation dependent, but must be at least

where
i ranges from 0 (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).
The initial value is GL_TEXTURE0.
Description
glActiveTexture selects which texture unit subsequent texture state calls will
affect. The number of texture units an implementation supports is
implementation dependent, but must be at least 48.
Errors
GL_INVALID_ENUM is generated if texture is not one of
GL_TEXTUREi,
where i ranges from 0 to (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).
Associated Gets
