|

|
|
|
//
|
|
|
|
|
// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,
|
|
|
|
|
// which proved to be endless problems for users.
|
|
|
|
|
// Our loader is custom-generated, based on gl3w but automatically filtered to only include
|
|
|
|
|
// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
|
|
|
|
|
//
|
|
|
|
|
// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.
|
|
|
|
|
// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
