//opengl 3 deprecation

. Application-generated object names - the names of all object types, such as
buffer, query, and texture objects, must be generated using the corresponding
Gen* commands. Trying to bind an object name not returned by a Gen*
command will result in an INVALID OPERATION error. This behavior is
already the case for framebuffer, renderbuffer, and vertex array objects. Object
types which have default objects (objects named zero) , such as vertex
array, framebuffer, and texture objects, may also bind the default object, even
though it is not returned by Gen*.

. OpenGL Shading Language versions 1.10 and 1.20. These versions of the
shading language depend on many API features that have also been deprecated.

. Pixel transfer modes and operations - all pixel transfer modes, including
pixel maps, shift and bias, color table lookup, color matrix, and convolution
commands and state, and all associated state and commands defining
that state.

. Legacy OpenGL 1.0 pixel formats - the values 1, 2, 3, and 4 are no longer
accepted as internal formats by TexImage* or any other command taking
an internal format argument. The initial internal format of a texel array is
RGBA instead of 1.

. Texture borders - the border value to TexImage* must always be zero, or
an INVALID VALUE error is generated (section 3.8.1); all language in section
3.8 referring to nonzero border widths during texture image specification
and texture sampling; and all associated state.
