/*
//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 .
