@subsection window_sizelimits Window size limits
The minimum and maximum size of the client area of a windowed mode window can be
set with @ref glfwSetWindowSizeLimits. The user may resize the window to any
size and aspect ratio within the specified limits, unless the aspect ratio is
also set.
@code
glfwSetWindowSizeLimits(window, 200, 200, 400, 400);
@endcode
To disable size limits for a window, set them to `GLFW_DONT_CARE`.
@code
glfwSetWindowSizeLimits(window, GLFW_DONT_CARE, GLFW_DONT_CARE, GLFW_DONT_CARE, GLFW_DONT_CARE);
@endcode
The aspect ratio of the client area of a windowed mode window can be set with
@ref glfwSetWindowAspectRatio. The user may resize the window freely unless
size limits are also set, but the size will be constrained to maintain the
aspect ratio.
The aspect ratio is specified as a numerator and denominator, corresponding to
the width and height, respectively.
@code
glfwSetWindowAspectRatio(window, 16, 9);
@endcode
To disable aspect ratio for a window, set it to `GLFW_DONT_CARE`.
@code
glfwSetWindowAspectRatio(window, GLFW_DONT_CARE, GLFW_DONT_CARE);
@endcode
You can have both size limits and aspect ratio set for a window, but the results
are undefined if they conflict.

The position of a windowed-mode window can be changed with @ref
