glCreateBuffers and OpenGL 4.4

[Dressingoak]

Hi,
We should make it clear what OpenGL copatability the project should have. The moment we changed glGenBuffers to glCreateBuffers things went south (for me) with the exception:

Exception thrown at 0x0000000000000000 in Sandbox.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

Some quick research suggested that it's sue to me running OpenGL 4.4 on my laptop. This of course means that the solution does not run out-of-the-box in this case, and based on what I've read, it's due to GL_ARB_direct_state_access entering the core profile only as of 4.5. So:

• Are there any reasons for not sticking with glGenBuffers ?
• Might it be worth differentiating the implementation based on the GL version?
• Should anything below 4.5 be unsupported all together?

"Are there any reasons for not sticking with glGenBuffers ?"
I believe that he used glCreateBuffers just to match the same function names for generating buffers and shader. As he shown, glCreateBuffers does not bind the buffers as he expected.
The difference between glCreate and glGen is that glCreate returns buffers that are completely new and unused, unlike glGen, which reuse buffer names.
Somebody please correct me if i'm wrong, but there is no practical difference between glGen and glCreate

"Might it be worth differentiating the implementation based on the GL version?"
"Should anything below 4.5 be unsupported all together?"
I really don't see a reason for that. You could base your build on the GL version, but I don't think that is really necessary to limit the build to a GL version so recent. Older versions still working pretty fine

Ps: please forgive my english. It is far from ideal, i'm still working on it

glCreateBuffers is useful when working with other functions in GL_ARB_direct_state_access, such as glBindNamedBuffer. Since it's not being used at the moment, there is no difference. See #66.

Edit: In the Vertex Arrays episode, he said that we would not use this right now. So it should be switched to glGenBuffers.

This was fixed in #137
