omar c2fc978983 Style: Default style is now StyleColorsDark()! Toward a 1.60 release :) ()
omar 0734a12d25 IO: ImGuiConfigFlags_NoMouse disable hovering so it is not destructive. Amend 2464e62a1a
omar e88fb10d7c NewFrame: Extract some code into a NewFrameUpdateHoveredWindowAndCaptureFlags() which can be of use with touch-based inputs systems.
omar c1bdab6d5b Comments about io.WantCapture flags + todo entries.
omar ac2027c415 NewFrame: Extract some code into a NewFrameUpdateMouseInputs function. Moved settings saving higher up in the function so it is next to its peers.
omar 2464e62a1a IO: Added ImGuiConfigFlags_NoMouse to force clear/disable mouse inputs in NewFrame().
omar 18a243bef0 Columns: Fixed calling Columns() again with the same number of columns. ()

omar c23b5463c7 Viewport: Moving a window accross viewports tries to preserve the dragging pivot (that is assuming that the window will be evenly scaled by DPI, aka Style is scaled). ()

omar fc30462f18 Hide new windows for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. ()
omar 5aa3f99b4c Internal: using more consistent comparaison with HiddenFrames to not imply it could be -1. Tweaked comments.
omar 4649967112 Added extra comments and assertions to avoid user combining ImGuiCond flags. ()
omar cd1e6e384f Tooltip windows uses PopupBorderSize () + commented out debug stuff.
omar 1e116e6c17 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.
omar 84fbc49403 BeginChild: named child don't include the full id inside their name ()
omar 78610a54d2 Fixed Clang zealous cast-call warning (on par with GCC) which decided to warn against explicit C-style casts now.

omar cc96477b1c Comments ()
omar ac8931b2e9 Viewport: Moved OverlayDrawList to be a per-viewport instead of being global + fix overlay clipping glitch during viewport creation frame + support for software mouse cursor stradding over multiple viewport. The overlay draw list move is rather important as draw lists are not shared among viewports anymore and we can do a swap of their data without copying it. ()
omar 4f112f898e Viewport: Avoid modifying MousePos in UpdateWindowViewport just for the sake of docking test, sheering MousePos during the frame is problematic + minor renaming. ()
omar b69dc45f6e Internals: Removed ImGuiDataType_Float2.
omar c19b27813d Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. () May transition the other InputXXX function to use format strings as well.
omar c796960ff9 InputFloat: Scientific input. InputText: Added ImGuiInputTextFlags_CharsScientific to add 'e' 'E' to list of characters that can be input. (later useful for )
omar 21ac470a8a Nav: Fixed a crash with IMGUI_DEBUG_NAV_SCORING enabled + added info to Metrics.
omar e5ba982be0 Nav: Fixed a crash with IMGUI_DEBUG_NAV_SCORING enabled + added info to Metrics.

omar d1c45db9e8 Fixed enum typo.
omar c00523dba4 Viewport: Added extra Metrics and debug features.
omar 9d5ec05150 Viewport, Platform: Update the contents of GetPlatformData() in EndFrame() so back-end can access it even if UpdatePlatformWindows hasn't been called. ()
omar 2fecd332fc Viewport, Platform: Added void* to render/swap buffer functions. Comments. (, )
omar 62e94717eb Nav: InputText: Allow editing text input fields with NavActivate (space). Not sure about that, on one hand it feels more consistent but you can't finish the editing with space to double space (activate + input space) could feel inconsistent. ()
omar 33ad8b2f0c Nav: Track nav input source more generally (gamepad vs keyboard) () + update todos and demo tweaks
omar 46b61427e1 Viewport, Platform: Refactored platform interface. Removed need to use imgui_internal.h in backends. Split viewport into public facing ImGuiViewport and internal structure. Exposing enough data to provide custom tweaked renderers. Renamed handlers, fixed lots of inconsistencies. (, )
omar 1ab236d9df Viewport, Platform: Internal renaming to use more consistent (OsDesktopPos > PlatformPos). ()
omar 8364d1ca6c Viewport: Removed back-end renderer code that implied we need to clear with WindowBg color. Added NoRendererClear flag. (, )
omar 6e58a95a01 Viewport, Platform, Examples: Changes to resizing flow + restored support for Platform events affecting the ImGui windows (so Decorated windows are functional). (, ) ..
SDL: Added platform move/resize/close support.
GLFW: Added platform move/resize support. Moved Close to use callback for consistency.
Win32:
Vulkan: Fixed resize support.
Naming is WIP "PlatforrmRequestXXX" is too ambiguous. Basically we either have a ImGui->Platform flow or a Platform->ImGui flow. Working a bigger refactor now.
omar 207ad45983 Metrics: Displaying all draw lists of a window (if it uses layer 0 and has already been appended to earlier in the frame).
omar 921bb92eec Viewport: Fixed software mouse cursor from appearing in all multiple lists simultaneously. ()

omar f6fc28dfd2 Merge branch 'master' into viewport (inc Vulkan resize fix merge )
omar e7670c0bcc Style: CloseButton() now display a proper cross. Using Button colors for background. Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. ()
omar b9ac127b0b Internals: Columns renaming fields
omar 5e63711084 Viewport, DPI: Some early work on per-viewport DPI support. At the moment the easiest way is to replace fonts during the ChangedViewport callback, but down the line we should aim at handling some of it at ImFont level. (, )
omar a2fbcc9ad4 Examples: DPI: Portable DPI related helpers in the _Win32 examples. Using one in examples's main.cpp, the GetDpiScale functions are not wired anywhere for now. (, )
omar 10030ff3ec Viewport: Fix dropping back viewport not being moved to the front of the window list. (Now that viewport are more tighly coupled to a single root window) ()
omar 648735a4cf Viewport, DPI: Don't activate current window until a viewport has been selected. At this point we'll have the proper size/scale for the current DPI + fix viewport callback when appending to an existing window more than once a frame. (, )
omar a4629b0b36 Viewport, DPI: Select viewport before locking style sizes and before handling double-click-on-title-bar to collapse. (, )
omar 64cbbed152 Merge branch 'master' into viewport
omar 43f375b2f2 Viewport,Platform: Added GetWindowDpiScale() platform interface, changes of scale are reflected by positioning and resizing windows in their given viewport. ()
omar 351b3fa7b0 Updated Changelog following merge of + fixed entry added to wrong version Changelog in 1ef1acbd8d
omar 4d46383100 Viewport: Coupling non-main viewport to one window. Viewport name derived from the window. Added ImGuiConfigFlags_PlatformNoTaskBar, off by default (aka re-established task-bars by default for now). ()

omar cea7492bab Render: Removed the code that disable render if style.Alpha is 0.0f, it is both incorrect (as style Alpha can be modified mid-frame), not really necessary (just tested that full Alpha = 0 will lead to empty draw lists!) and misleading (bulk of the work was already done).
omar 8e3274e137 Viewport: Tracking current viewport we are appending to + added callback in PlatformInterface for DPI purpose (WIP). ()
omar 51afaf7117 Fixed type cast warning.
omar 0ec356eb6e Comments, FAQ update.
omar 5ed45d0aec Columns: Fixed destructive small resize. (). The OffsetNorm clamp introduced by was ok as it didn't write back into the storage, which started doing making it destructive. Right now I don't think the clamp is needed at all. It had uses (eg: hide the issue fixed by bf7481eba0).
omar bf7481eba0 Columns: Extent stop at the right-most clipped pixel. The right-most column might appear a little wider but it's usable space matches the others. (). +9 Internal: Store InnerClipRect.
omar 968a8d2a3f Columns: Clamping MaxX above MinX. This shouldn't have much of a benefit / affect, but the internal values are more sane this way. ()

Emmanuel Benoît 77a310736d Horizontal mouse wheel support
This patch adds support for the horizontal mouse wheel in ImGui. It
affects windows that can be scrolled, as long as the Ctrl key is not
being pressed.

The scrolling speed has been set empirically so that it matches the
scrolling speed on the Firefox browser when the horizontal wheel is
used.

Internally, it adds a MouseHorizWheel to ImGuiIO, which is then used in
NewFrame to scroll the current window.

The SDL/GL2, SDL/GL3, GLFW/GL2 and GLFW/GL3 examples has been modified
to use it.
