Subject: add GLFW error callback function and assertion
X-Git-Url: https://git.osiis.dedyn.io/?a=commitdiff_plain;h=refs%2Fpull%2F61%2Fhead;p=jp%2Fvkvg.git

add GLFW error callback function and assertion

Added a `glfwInit()` assertion because it could fail, and a callback function to get the error description and print it to stdout.
