Internals: Selectable: Renamed variables. Todo update.

Internals: PushItemFlag() flags are inherited by BeginChild().

Documentation: FAQ, ID Stack, Fonts (#1839, #1840), #1842)

Missing examples changelog bits and todo list

Examples: OpenGL3: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state. (#1836)

Drag and Drop: Source doesn't report as hovered (at a lower-level). Source disable AllowOverlap flag if any set. (#143)

Examples: iOS: Fixed missing call to CreateContext() + various shallow coding style tweaks. (#1835)

Drag and Drop: BeginDragDropSource(): Offset tooltip position so it is off the mouse cursor, but also closer to it than regular tooltips, and not clamped by viewport. (#1739)

BeginCombo(), BeginMainMenuBar(), BeginChildFrame(): restore modified style at end of Begin instead of End so doesn't affect child windows, BeginTooltip() etc.. (allowed since 7b6b703)

Examples: Comments about GLSL version not being the same as GL context version. (#1828)

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.
