Remove call to glFlush() before swap_buffers
We may not want to call `swap_buffers` in the same thread as the current thread, so we're moving the call to `glFlush` out of the scope of glutin.

### Win32
|
||||
|
||||
- You must call `glFlush` before `swap_buffers`, or else on Windows 8 nothing will be visible on the window
|
||||
- Pixel formats are not implemented
|
||||
- If you don't have MinGW installed, you will need to provide `libgdi32.a` and `libopengl32.a` ; you can put them in `C:\Users\you\.rust`
|
||||
- If you don't have `make` in your PATH, you can pass `--no-default-features --features "window"` when compiling ([see also](http://crates.io/manifest.html#the-[features]-section))
