Blender 2.8: OpenGL: replace old GL with the new immediate API in UI_draw_roundbox_gl_mode

I change UI_draw_roundbox_gl_mode to use immediate API.
The rest of the change is the call to the function.
I also make some change in UI_ThemeColor4(int colorid) for eg to make convenience to use.
I would really like to know if it's the good way to do, if yes I will make all the change in the node_daw.c after, else say me what's wrong and how to deal with color else.
