     On Windows, SOKOL_DLL will define SOKOL_APP_API_DECL as __declspec(dllexport)

+    if SOKOL_WIN32_FORCE_MAIN and SOKOL_WIN32_FORCE_WINMAIN are both defined,
+    it is up to the developer to define the desired subsystem.

     On Linux, SOKOL_GLCORE can use either GLX or EGL.
     GLX is default, set SOKOL_FORCE_EGL to override.
