fix window extent after creating

The requested dimensions of a newly created window may be different
from the actual dimensions as the window system may enforce additional
restrictions. This happens, for example, when using Wayland with a
scaling factor of 3 (the default width of 800 is not divisible by 3).

To fix it, just re-query the actual framebuffer size after creating the window.
The GLFW documentation also suggests to do this:

> The created window, framebuffer and context may differ from what you requested,
> as not all parameters and hints are hard constraints. This includes the size of
> the window, especially for full screen windows. To query the actual attributes
> of the created window, framebuffer and context, see glfwGetWindowAttrib,
> glfwGetWindowSize and glfwGetFramebufferSize.

-- https://www.glfw.org/docs/3.3/group__window.html#ga3555a418df92ad53f917597fe2f64aeb

This should be a better fix for #192
