/*! @page window Window handling
 
@tableofcontents

The primary purpose of GLFW is to provide a simple interface to window
management and OpenGL and OpenGL ES context creation.  GLFW supports
multiple windows, which can be either a normal desktop window or
a fullscreen window.

@section window_hints Window hints

There are a number of hints that can be set before the creation of a window.
Some affect the window itself, others its framebuffer or context.  These hints
are set to their default values each time the library is initialized with @ref
glfwInit, can be individually set with @ref glfwWindowHint and reset all at once
to their defaults with @ref glfwDefaultWindowHints.

Note again that they need to be set *before* the creation of the window you wish
to have the specified properties.


@subsection window_hints_hard Hard and soft constraints

Some window hints are hard constraints.  These must match the available
capabilities *exactly* for window and context creation to succeed.  Hints
that are not hard constraints are matched as closely as possible, but the
resulting window and context may differ from what these hints requested.  To
find out the actual parameters of the created window and context, use the
@ref glfwGetWindowParam function.

The following hints are hard constraints:
- `GLFW_STEREO`
- `GLFW_CLIENT_API`

The following additional hints are hard constraints if requesting an OpenGL
context:
- `GLFW_OPENGL_FORWARD_COMPAT`
- `GLFW_OPENGL_PROFILE`

Hints that do not apply to a given type of window or context are ignored.


@subsection window_hints_fb Framebuffer related hints

The `GLFW_RED_BITS`, `GLFW_GREEN_BITS`, `GLFW_BLUE_BITS`, `GLFW_ALPHA_BITS`,
`GLFW_DEPTH_BITS` and `GLFW_STENCIL_BITS` hints specify the desired bit
depths of the various components of the default framebuffer.

The `GLFW_ACCUM_RED_BITS`, `GLFW_ACCUM_GREEN_BITS`, `GLFW_ACCUM_BLUE_BITS`
and `GLFW_ACCUM_ALPHA_BITS` hints specify the desired bit depths of the
various components of the accumulation buffer.

The `GLFW_AUX_BUFFERS` hint specifies the desired number of auxiliary
buffers.

The `GLFW_STEREO` hint specifies whether to use stereoscopic rendering.

The `GLFW_SAMPLES` hint specifies the desired number of samples to use for
multisampling.

The `GLFW_SRGB_CAPABLE` hint specifies whether the framebuffer should be
sRGB capable.


@subsection window_hints_ctx Context related hints

The `GLFW_CLIENT_API` hint specifies which client API to create the context
for.  Possible values are `GLFW_OPENGL_API` and `GLFW_OPENGL_ES_API`.

The `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` hints
specify the client API version that the created context must be compatible
with.

For OpenGL, these hints are *not* hard constraints, as they don't have to
match exactly, but @ref glfwCreateWindow will still fail if the resulting
OpenGL version is less than the one requested.  It is therefore perfectly
safe to use the default of version 1.0 for legacy code and you will still
get backwards-compatible contexts of version 3.0 and above when available.

For OpenGL ES, these hints are hard constraints, as there is no backward
compatibility between OpenGL ES versions.

If an OpenGL context is requested, the `GLFW_OPENGL_FORWARD_COMPAT` hint
specifies whether the OpenGL context should be forward-compatible, i.e. one
where all functionality deprecated in the requested version of OpenGL is
removed.  This may only be used if the requested OpenGL version is 3.0 or
above.  If another client API is requested, this hint is ignored.

If an OpenGL context is requested, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
specifies whether to create a debug OpenGL context, which may have
additional error and performance issue reporting functionality.  If another
client API is requested, this hint is ignored.

If an OpenGL context is requested, the `GLFW_OPENGL_PROFILE` hint specifies
which OpenGL profile to create the context for.  Possible values are one of
`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE`, or
`GLFW_OPENGL_NO_PROFILE` to not request a specific profile.  If requesting
an OpenGL version below 3.2, `GLFW_OPENGL_NO_PROFILE` must be used.  If
another client API is requested, this hint is ignored.

The `GLFW_CONTEXT_ROBUSTNESS` hint specifies the robustness strategy to be
used by the context.  This can be one of `GLFW_NO_RESET_NOTIFICATION` or
`GLFW_LOSE_CONTEXT_ON_RESET`, or `GLFW_NO_ROBUSTNESS` to not request
a robustness strategy.


@subsection window_hints_wnd Window related hints

The `GLFW_RESIZABLE` hint specifies whether the window will be resizable by
the user.  The window will still be resizable using the @ref
glfwSetWindowSize function.  This hint is ignored for fullscreen windows.

The `GLFW_VISIBLE` hint specifies whether the window will be initially
visible.  This hint is ignored for fullscreen windows.
