Internals: Child windows that are clipped or part of a collapsed parent are not marked as collapsed anymore, but just a separate hidden marker set. We distinguish hiding for size measurement vs hiding for other reasons. Cleaned a little the end of Begin.

Nav: Tweaked CTRL+TAB to hide visual noise on fast switch + fading out screen dimming and highlight to make the experience less harsh

FAQ update

Internals: SplitterBehavior() added hover_visibility_delay parameter which is helpful to reduce visual noise. (#319)

Made it possible to move a window by dragging from the Collapse button (past the drag threshold). Extracted some code out to a CollapseButton() function.

Internals: Renamed one of the arrow functions so their name don't collide.

Examples: Using fully qualified "Dear ImGui" name in window titles.

Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)

Internals: Extracted part of NewFrame() into a UpdateMouseWheel() function.

Added asserts to catch illegal modifications of the font atlas between NewFrame() and EndFrame()/Render(). (#1958)

Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.

Readme: fixed typo + patron

Ignore GCC warning (-Wclass-memaccess) in imgui.h (#1959)

Tweaked Contributing guidelines, Issue and PR templates

ImGuiTextFilter, TextRange: removed cruft from TextRange since it's not a publicly and generic helper at the moment + marked internal stuff + changed a reference to a pointer. (#1879)

Examples: SDL: Removed SDL_HAS_WARP_MOUSE_GLOBAL in the non-viewport branch. (#1954) (+1 squashed commits)

Nav: Fixed CTRL+TAB windowing list from always showing the implicit Debug window. (#787)

Fix warning when IMGUI_DEFINE_MATH_OPERATORS is already defined by build system. (#1950)

Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section. This will be of more importance with the introduction of tabs.

Demo: Fixed spacing from b629f90 change.

Examples: Tweaked the main.cpp example structure for all examples. (There are a few hidden agendas here: 1) I would like to avoid encouraging people from using the implicit "Debug" window, and promote using Begin/End. In spite of my best attempt, there are a few feature of the upcoming docking system that cannot work 100% properly for the implicit Debug window, so future proof let's not put that feature in the spotlight too much for new users. 2) Moved dumb hardcoded positions into a single spot that can be replaced with a viewport relative position and not affect other demo windows. 3) Calling ShowDemoWindow before anything else, also for the benefit of a specific docking demo which will have an ordering constraint which is not really problematic in a real app but shouldn't be put forward in the demo.

Examples: DX10, DX11: Fixed unreleased resources in Init and Shutdown functions. (#1944)

Demo: Spacing.

Demo: Re-ordered example app code to match their menu order and forward declaration order + added header to delimitate them.

Comments, exposed a few things in imgui_internal.h for consistency, added ImQsort wrapper.

Revert part of c7016c2 incorrectly renaming ImGuiCol_NavWindowingHighlight to ImGuiCol_NavWindowListHighlight, that was wholly unnecessary (and not documented!). (also invalidate #1939)

Examples: include for intptr_t on tdm-gcc + mingw32 (#1936) + mouse buttons comments

IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211) ...

+ shallow changelog tweaks

Examples: OpenGL3: Added shaders more versions of GLSL + made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac. (#1938, #1900, #1513, #1466, etc.)

Fixed missing value in GetStyleColorName(). (#1939) broken with c7016c2
