  Q: How can I use my own math types instead of ImVec2/ImVec4?
  A: You can edit imconfig.h and setup the IM_VEC2_CLASS_EXTRA/IM_VEC4_CLASS_EXTRA macros to add implicit type conversions.
-    This way you'll be able to use your own types everywhere, e.g. passsing glm::vec2 to ImGui functions instead of ImVec2.
