e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
node open/closed state differently. See what makes more sense in your situation!
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.
Q: How can I load a different font than the default?
A: Use the font atlas to load the TTF/OTF file you want:
ImGuiIO& io = ImGui::GetIO();
