Added IsAnyWindowFocused(). Renamed IsMouseHoveringAnyWindow() -> IsAnyWindowHovered(), IsPosHoveringAnyWindow() -> IsAnyWindowHoveredAtPos(), IsMouseHoveringWindow() -> IsWindowHoveredRect() for consistency. Kept inline rediection function.

  Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
  Also read releases logs https://github.com/ocornut/imgui/releases for more details.
 
+ - 2016/07/18 (1.50) - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
+                     - renamed IsPosHoveringAnyWindow() to IsAnyWindowHoveredAtPos() for consistency. Kept inline redirection function (will obsolete).
+                     - renamed IsMouseHoveringWindow() to IsWindowHoveredRect() for consistency. Kept inline redirection function (will obsolete).
  - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. 
                        If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. 
                        However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.

  A: You can read the 'io.WantCaptureXXX' flags in the ImGuiIO structure. Preferably read them after calling ImGui::NewFrame() to avoid those flags lagging by one frame, but either should be fine.
     When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application.
     When 'io.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available.
-    ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsMouseHoveringAnyWindow().
+    ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsAnyWindowHovered().
     (Advanced note: text input releases focus on Return 'KeyDown', so the following Return 'KeyUp' event that your application receive will typically have 'io.WantcaptureKeyboard=false'. 
      Depending on your application logic it may or not be inconvenient. You might want to track which key-downs were for ImGui (e.g. with an array of bool) and filter out the corresponding key-ups.)
