Examples: GLFW: Made it possible to Shutdown/Init the backend again (by reseting the time storage properly). Changelog. Added to Vulkan example. (#1827)

Examples: GLFW* Make subsequent window creation possible.

ColorEdit3, ColorEdit4, ColorButton: Added ImGuiColorEditFlags_NoDragDrop flag to disable ColorEditX as drag target and ColorButton as drag source. (#1826)

ImVector: added erase(it first, it last) helper. Added erase_unsorted(it) helper. + todo fixes/additions

Fixed GCC pre-8 build. (#1822) + added bonus the non-ASCII character pasted from GCC breaks my SourceTree/Git combo

Disabled GCC 8.1.0 warnings -Wclass-memaccess (#1822)

Remove trailing white spaces.

Internals: Forward declaring and commenting internal structures. Renamed ImGuiDrawContext to ImGuiWindowTempData, but kept .DC member name for backward compatibility purpose

Comments + Internals: Selectable: decoupled internal flags and removed their menu / menu-item semantic as upcoming changes are requiring more flexibility.

TreeNode: Fixed nodes with ImGuiTreeNodeFlags_Leaf flag always returning true which was meaningless. Tweak demo.

Nav: Draft internal api to forward move request with loop/wrap options. Will rework for parallel scoring of two paths (as a generalization of the NavFlattened concept). (#787)

Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787)

Version 1.62 WIP

ImVector: Tweaked reserve() flow to avoid calling MemFree(NULL) which is unnecessary. (#1796)

Examples: OpenGL3: Trying to make the call to glBindSampler optional to make the example code easier to use/share with different context version. (#1806)

Version 1.61 + todo additions

Demo: Tweaked custom rendering custom, added a Thickness drag. Clarified use of vertical/horizontal line. Add a single pixel demo (wowow)

ColorEdit: Fixed not being able to pass the ImGuiColorEditFlags_NoAlpha or ImGuiColorEditFlags_HDR flags to SetColorEditOptions(). Demo tweak.

Fix for atof with glibc.

Added ImAtof, ImCeil, ImFloorStd to IMGUI_DISABLE_MATH_FUNCTIONS for consistency. Configuration comments.

Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it slightly easier to redefine wrappers to std maths functions such as fabsf(), fmodf(), etc. Comments.

Comments about AddConvexPolyFilled(), PathFillConvex() requiring a clockwise order path. (#1811)

Update README.md

Demo: Fixing build due to using INT_MAX, UINT_MAX, LLONG_MAX, ULLONG_MAX.

Demo: Renamed "fixed overlay" to "simple overlay" because it's not fixed any more!

Demo: Added demo for DragScalar(), InputScalar(), SliderScalar(). (#643)

Data types: DragScalar: Fixed speed of integer values tweaking with keyboard/gamepad when speed < 1. Enforce min/max bounds when power curves are used. SliderScalar: Fixed integer/slow tweaking. (#643)

Data types: DragScalar, InputScalar: default parameters. Added IM_STATIC_ASSERT(). Comments.

Documentation tweaks, comments
