// No FLAG_MSAA_4X_HINT: on some GPU/driver combinations (seen with an
// NVIDIA PRIME-offloaded context) GLFW's GLX context request for a
// 4x-multisample framebuffer fails outright ("GLX: Failed to create
// context: BadValue"), and raylib/GLFW then segfaults using the broken
// context instead of falling back cleanly. Not worth the crash risk for
// a cosmetic antialiasing hint.
//
// FLAG_WINDOW_HIGHDPI: macOS/GLFW always backs the window with a
// full-resolution Retina framebuffer (rglfw.c's _GLFW_USE_RETINA),
// regardless of this flag -- but rlImGui only reads that real scale
// factor into io.DisplayFramebufferScale (and scales its font atlas
// and mouse coordinates to match) when FLAG_WINDOW_HIGHDPI is set.
// Without it, on a Retina display ImGui assumes 1:1 and everything it
// draws ends up scaled/positioned for a framebuffer a quarter the
// actual size -- menus stretched into oversized black bars, widgets
// rendered as solid blocks from a mis-sampled font atlas.
