Drawing primitive directly doesn't cause any problems, it could be a state that doesn't get reset

It looks like that the last vertex is missing.
I've tested it on MacOSX 10.11.6, here are the details of the GPU

Right now is a testing app for joysticks, theirs hot-plugging and the keyboard.
It should be a simple example like the other ones

deps is becoming the canonical dependency manager.

We are currently not using a camera to control the view matrix.
To be able to scroll over a bigger level we need to implement something that will contain the projection matrix as well, since the zoom is done by that matrix.

Right now it's possible to use the keyboard only as a joystick replacement.
There should be a way of getting lower level access to the key events.

Currently, the library uses float32. It does so to pass data easily to OpenGL.
Go's math libraries use float64, Box2D uses float64, MathGL uses float64...
I think it would be easier to switch to float64 and avoid a lot of conversions and to cast to float32 only before passing data to OpenGL

Right now, drawing a quad with a single color via shader uniform doesn't work

Would be nice to start adding some simple tests and to have TravisCI run them

I've tried running the snake demo via:
go run demos/snake/main.go
but it gives this error:
# command-line-arguments demos/snake/main.go:24:10: undefined: newSnakeGame

golang has fairly good tooling to pull external libraries from github, all we need to do is:

• run go get -u github.com/ByteArena/box2d
• refer to that package in imports: import "ByteArena/box2d"
• add that information to README :)

Proper joystick mapping (from sdl2) is coming with glfw 3.3 which is 95% complete.
Instead of building something complex I am going to add support at least for the xbox360 and ps4 controllers, then we'll see

GLFW has not and will never have support for audio, we need a multiplatform library. It looks like the bindings for OpenAL are very old.
Another alternative is: https://github.com/gordonklaus/portaudio

Context should be renamed to something different, e.g., Renderer
As part of this change, some of the GL code we have spread around should be moving into Renderer

takes more than a second to just a.InitApp():

'Tiled' editor can create tiled maps but also maps composed by free form images. It can place triggers and entities.
It could be a good candidate to support a wide range of possible games

While adding support for framebuffers and postprocessing, I've found out that the following method call crashes the app:

gl.GenFramebuffers(1, &fb.fbo)

It looks like it's an issue of glfw, I am going to check their page to see if it's known

It looks like a problem of the Box2D implementation I'm using...
