DPI management impact in immediate draw

[deuxcents]

Hello
In Windows, glfw will give: glfwGetWindowSize = glfwGetFramebufferSize, even if glfwGetWindowContentScale is not 1.

On other os you can indeed have glfwGetWindowSize = glfwGetFramebufferSize / glfwGetWindowContentScale like your are doing in void gs_platform_framebuffer_size(uint32_t handle, uint32_t* w, uint32_t* h)

So in Windows this is what happens when I ask with a Windows 150% scale factor:
gs_app_desc_t{
.window_width = 800,
.window_height = 600}
glfw creates a 1200x900 pixel window, this is fine
I draw an immediate 10 pixel square. It measures on screen 15 pixel in Windows. It will measure 10pixel on mac os x i suppose.
immediate set OpenGL viewport based on gs_platform_framebuffer_size which in windows will give me a viewport of 1800x900 exlaining the zoom of my square.

Question : should the user handle dpi on his side ?

If yes you should just call glfwGetFramebufferSize in gs_platform_framebuffer_size. For Camera2D maybe you need to call the framebuffer size instead of the window size (you need to think of all gs_platform_window_size calls).

One last thing : can you please add the glfw window create hint GLFW_SCALE_TO_MONITOR as a gs window option like GLFW_RESIZABLE ?
