Begin: Handle manual resize (grip, border, gamepad) before setting up window DrawList main clipping rectangle. Sane (and required for viewport code). (#822, #1542)

MovingWindow: Proper fix for 651538e attempt, without altering MovingWindow which has side-effects. Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else. (ref #1381, #1337)

Revert "Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else. (ref #1381, #1337)" ...

This reverts commit 651538e.

Begin: Shuffling bits of code around.

Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else. (ref #1381, #1337)

Demo: Using IM_COL32() instead of ImColor() in ImDrawList centric contexts.

Demo: Tweaks format.

Made obsolete IsAnyWindowHovered()/IsAnyWindowFocused() static inline. static only tends to trigger warnings. (#1382)

Added ImGuiHoveredFlags_AnyWindow, ImGuiFocusedFlags_AnyWindow. Obsoleted IsAnyWindowHovered()/IsAnyWindowFocused() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow)/IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Added to demo. (#1382)

Internals: Begin: Refactor some code into an UpdateManualResize() function.

Internals: Begin: Moved DrawList setup code below, the viewport system will need to push the outer clipping rectangle as late as possible.

Begin: Moving some code around for the benefits of the wip viewport branch.

Internals: Using ImFloor().when appropriate.

Internals: Rect: Added ClipWillFull helper + comments on variations.

Internals: ImVec2 versions of ImMin, ImMax inline float version for a faster full-on-debug-no-inline experience.

InputText: Added alternative clipboard shortcuts: Shift+Delete (cut), Ctrl+Insert (copy), Shift+Insert (paste). (#1541)

InputText: Moved code for checking clipboard shortcut so we can expand on it. (#1541)

Added ImGuiKey_Insert for future use. Setup in all example bindings. (#1541)

Examples: OpenGL3+GLFW: Using 3.2 context + GLSL version 150 (#1466)

Examples: OpenGL3+SDL: Changed GLSL shader version to 150 (#1466, #1504)

Popups: Comments, reorganize bits of the header section, renamed parameters.

BeginPopup: Exposed extra_flags publicly. (#1533)

OpenPopup(): Always reopen existing popup. Removed OpenPopupEx() bool reopen_existing which is always true. This also makes the public API on par with OpenPopupEx(). (#1497, #1533)

Popups: Gently handle the user mistakenly calling OpenPopup() every frame. (when reopen_existing is true). (#1497)

Internals: Popup: Renaming fields.

Popup, Menus: Tweaks and comments.

Internals: Popup: Explicitely setting up ImGuiPopupRef reduces confusion.

Popups: Revert aca23fd (Oct 20, 2017). Because 1) I can't seem to find a default. 2) The if is definitively faulty and would have been all true. 3) It looks like possibly the following commit 6ab737a could have made this unnecessary. Not absolutly certain. (~#439)

Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse click. Note that they don't use the full ButtonBehavior() or tracking aabb on both click and release. Applications I've tried seems to behave inconsistently there but on-release-without-tracking is both fairly common and doesn't require extra code for the id tracking. (~#439)

Internal: ButtonBehavior: Tweak to update g.ActiveIdClickOffset more consistently
