Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) in every other back-ends. (fixes 6cee2fca)  (#1733, ~#1731) + assert

IO: ImGuiConfigFlags_NoMouse disable hovering so it is not destructive. Amend 2464e62a

NewFrame: Extract some code into a NewFrameUpdateHoveredWindowAndCaptureFlags() which can be of use with touch-based inputs systems.

NewFrame: Extract some code into a NewFrameUpdateMouseInputs function. Moved settings saving higher up in the function so it is next to its peers.

Renamed ImGuiConfigFlags_NoSetMouseCursor to ImGuiConfigFlags_NoMouseCursorChange. Followup to 75c3793d two weeks ago. (#787, #1495, #1202) + comments

Hide new windows for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. (#1694)

Internal: using more consistent comparaison with HiddenFrames to not imply it could be -1. Tweaked comments.

Removed need for -Wnocast-qual on modern Clang/Xcode as a token of good behavior. Unfortunately the old stb_ decompress code is a little const clunky.  + warning fix in stb_textedit which is already in master afaik.

Fixed Clang zealous cast-call warning (on par with GCC) which decided to warn against explicit C-style casts now.

Examples: Win32: Fixes for MingW which doesn't support a 2007 define? I have no idea why people still use MingW (#1704, #1463)

Examples: SDL: Note about SDL breaking the IME under Windows (I can't seem a way SDL2 Windows IME implementation can possibly work, the functions are never called/referenced).

Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011) May transition the other InputXXX function to use format strings as well.

InputFloat: Scientific input. InputText: Added ImGuiInputTextFlags_CharsScientific to add 'e' 'E' to list of characters that can be input. (later useful for #1011)

Examples: GLFW: Don't alter cursor mode if GLFW_CURSOR input mode is GLFW_CURSOR_DISABLED. (#1202) [@PhilCK]

IO: Added ImGuiConfigFlags_NoSetMouseCursors. Added ImGuiBackendFlags_HasMouseCursors, ImGuiBackendFlags_HasSetMousePos. (#787, #1495, #1202)

Added ImGuiBackendFlags for backend to expose its capabilities. Added ImGuiBackendFlags_HasGamepad. (#787, #1542)

IO: Renamed io.WantMoveMouse to io.WantSetMousePos (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch) + internal renaming (#787)

imconfig: Added IMGUI_STB_TRUETYPE_FILENAME, IMGUI_STB_RECT_PACK_FILENAME + documenting IMGUI_DISABLE_STB_XXX flags and hiding IMGUI_STB_NAMESPACE which is misleading.
Fixed typos in todo list.

Examples: Renamed applications to emphasis on use of GLFW as a platform framework + minor local tweaks
