comment What is a reasonable OpenGL version baseline for a mid-range 3D game?
@Nicol I actually used it for separate_shaders, subroutines and program_binary together. I didn't know subroutines are evil, as I only have 2.1 experience.

comment Learning OpenGL: Red and Blue book still relevant?
@bobobobo Well, it doesn't have only 1.1, it also treats newer features (upto 3.1, I think), but it also covers all of the old deprecated features, that just don't fit to modern OpenGL (and won't even work in a core context), istead of teaching the new and future way of OpenGL, like the newest edition of the SuperBible does.

comment How can I draw the depth value in GLSL?
Nice idea for a fixed-function pipeline, never thought about that.

comment Direct3D and OpenGL Matrix representation
OpenGL matrices are definitely NOT left-handed (and cooridnate systems neither).

You know there is no OpenGL 2.3, do you?

comment What is an OpenGL equivalent to ID3DXSprite?
You can use point sprites in OpenGL for which texture coordinates are generated automatically for the four corners. But I think point sprites are regarded deprecated, so your rectangle version is the method of choice (should be faster than gshader).
