Merge branch 'master' into context

ImVec2: added [] operator. This is becoming desirable for some types of code, better added sooner than later.

Drag and Drop: TreeNode as drop target displays rectangle over full frame. Added optional internal storage for item display rect. Will expose later. (#1597, #143)

Internals: TreeNode: Renaming local to be more consistent with other widgets.

Internals: Refactored bool LastItemRectHovered into flags. (#1597)

Examples: SDL: Using SDL_GetPerformanceCounter() / SDL_GetPerformanceFrequency() to handle framerate over 1000 fps properly. Noticed bad inputs artefacts in Nav branch at 2000 fps without this. (#996)

Examples: SDL2: Enabling vsync. Using scancode consistently, fixed keyboard weirdness.

Tooltip: BeginTooltip() sets NoInputs flag.

Style: Fixed missing style.MouseCursorScale initialization (#939), messed up original commit badly.

Merging the minor/shallow changes from Navigation branch.

Internals: ImRect: Added IsInverted() helper.

imgui_freetype: comments about correct blending and sRGB (#618, #578)

Removed root .gitignore. (#1594)

Merge pull request #1594 from gerryhernandez/fix-apple-example ...

Examples: Apple: Fix iOS code; fixes entire XCode build for Apple example

imgui_freetype: Documentation, tweaks. (#618)

Moved imgui_freetype from imgui_club (#618)

Style Added style.MouseCursorScale, may remove (#939).

Natvis: Showing some flags for ImGuiWindow.

CloseButton: Fixed cross positioning.

Internals: Renamed CloseInactivePopups() to a better ClosePopupsOverWindow(). Exposed in imgui_internal.h

Internal: Avoid needlessly bringing parent of front-most child back to front. This is mostly to reduce flicker/confusion in Metrics when traversing windows. We could aim at separating the child windows from non-child windows at some point.

Demo: Tweaked the Child demos, added a menu bar to the second child to test some navigation functions.

Log: Comments and extraneous assets to clarify intent. (#1584)

Style: Enable window border by default. (#707)
