Documentation

Examples: Vulkan: Viewport: Tweak to improve framerate on multiple-viewport situations, tho it is still halving the unthrottled framerate on nvidia for some reason.. Followup to 4dea032 (#1542)

Merge branch 'master' into viewport ...

# Conflicts:
#	imgui.cpp
#	imgui.h

Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections.

Examples: Viewport: Disabling swap intervals / vsync on secondary context to match what the DX11 bindings is doing. (#1542)

ImFontAtlas Comments (#2042) + added ImGuiFontAtlas_None for consistency.

Viewport: Fixed warnings due to bad merge.

Internals: Renaming of non-user facing parts from ValueChanged to Edited terminology. (#2034, #820, #956, #1875)

Comments, demo

Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete fast as IsItemDeactivatedAfterChange() is very recent). (#820, #956, #1875, #2034)

Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool returned by most widgets. It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034)

Internals: Wired a ImGuiItemStatusFlags_ValueChanged into ItemStatusFlags, for an hypothetical IsItemValueChanged() function. (#2034)

Rearrange header comments to find enums easily + fixed inconsistent sorting.

InputText: Improved sturdiness if the ResizeCallback purposefully modify data->BufTextLen or data->BufSize. (#2006, #1443, #1008)

InputText: Fix ResizeCallback callback on restoring initial value with Escape key. Avoid over-allocating for InitialText storage. (#2006, #1443, #1008)
