Earlier 7c5b0e82 broke with VS2015 and some other MingGW/GCC setups.

This reverts commit 7c5b0e82.

Only use required no. of types and sets

Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable stb_sprintf implementation (#6626)

Tooltips: fixed ImGuiHoveredFlags_ForTooltip conflicting with ImGuiHoveredFlags_NoNavOverride since 10c7709f. (#6622, #1485)

Tables: fixed GetContentRegionAvail().y report not taking account of lower cell padding or of using ImGuiTableFlags_NoHostExtendY. (#6619)

Made GetContentRegionMax() fully defer to WorkRect when inside a table container.

Tables: fixed calculation of multi-instance shared decoration/scrollbar width of scrolling tables. (#5920, #6619)

Avoid width variation when resizing down a table hosting a child window.
+ shallow tweak to GetContentRegionMax().

Backends: GLFW: revert support for GLFW_CURSOR_DISABLED, let user use ImGuiConfigFlags_NoMouse. (#5625, #6609)

Overlap, IsItemHovered: clarification on using IsItemHovered() on a non-reactive item after a reactive overlappable one. (#6610)

Works with one-frame delay inconsistent with other functions, may be too bug-prone.

Change for #6602 broke, supposedly because using old version of emsdk.
Initial reason for locking 3.1.37 was 3.1.38 had a bug, now fixed https://github.com/emscripten-core/emscripten/issues/19363

Our codebase requires VS2012+ since a while.

Doc: removed "generic" docking/viewport branch section of changelog since this is misleading. Will add formally when we reelase. (#2109, #1542)

ImDrawData: call _PopUnusedDrawCmd() later. as RenderDimmedBackgrounds() rely on a valid command being there (especially in docking branch). (#6406, #4879, #1878)

Amend/fix dbeeeae5 for docking.
+ Build fix when using IMGUI_DISABLE_DEBUG_TOOLS

ImDrawData: Slight refactor so internal logic uses same logic as AddDrawList().  (#6406, #4879, #1878)

# Conflicts:
#	imgui.cpp
#	imgui_internal.h

ImDrawData: changed CmdLists from raw array to ImVector<> owned by ImDrawData itself. Faclitate user-manipulation of the array (#6406, #4879, #1878) + deep swap. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)

+ Metrics: avoid misleadingly iterating all layers of DrawDataBuilder as everything is flattened into Layers[0] at this point.

# Conflicts:
#	imgui.cpp
#	imgui_internal.h

Nav: PageUp/PageDown always set NavJustMovedTo even when landing on same spot (which can trigger a selection).

This is mostly expected for range-select.
+ Rename ImGuiNavMoveFlags_Tabbing -> ImGuiNavMoveFlags_IsTabbing

Scrollbar: layout needs to take account of window border size, so a border size will slightly reduce scrollbar size. (#2522)

Rework/revert intent of c1a61d25.
