@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.

any size and aspect ratio within the specified limits, unless the aspect ratio
is also set.

To disable size limits for a window, set them to `GLFW_DONT_CARE`.
To specify only a minimum size or only a maximum one, set the other pair 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.
To disable size limits for a window, set them all to `GLFW_DONT_CARE`.
The aspect ratio is specified as a numerator and denominator, corresponding to
the width and height, respectively.
The aspect ratio of the client area of a windowed mode window can be enforced
with @ref glfwSetWindowAspectRatio. The user may resize the window freely
unless size limits are also set, but the size will be constrained to maintain

@code

@endcode
To disable aspect ratio for a window, set it to `GLFW_DONT_CARE`.
The aspect ratio is specified as a numerator and denominator, corresponding to
the width and height, respectively. If you want a window to maintain its
current aspect ratio, simply use its current size as the ratio.
@code
glfwSetWindowAspectRatio(window, GLFW_DONT_CARE, GLFW_DONT_CARE);
int width, height;
glfwGetWindowSize(window, &width, &height);
glfwSetWindowAspectRatio(window, width, height);
@endcode
To disable the aspect ratio limit for a window, set both terms to
`GLFW_DONT_CARE`.
You can have both size limits and aspect ratio set for a window, but the results
are undefined if they conflict.
