Silencing -Wstack-protector (#2459)

Examples: DirectX9: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects(). FreeType: Fixed suggested code to not require an initial build call.. (#2454)

Examples: DirectX12: Various tidying up.

Examples: OpenGL3: Minor tweaks, clarifications + not calling glBindBuffer more than necessary in the render loop.

Internals: Renamed the ImGuiWindow HiddenFrameXXX fields to decorrelate them from resizing behavior, as those values are set by other logic.

Comments (#2441) + Freeglut fixes (#2430)

Rearrange code in UpdateMouseWheel(). (#2424, #1463) + Fix old io.FontAllowUserScaling feature (probably should be made obsolete, but until then best fixed)

Implement horizontal scrolling with Shift+Scroll ...

This is standard scrolling behaviour in most applications.

InputText: Fixed selection background starts rendering one frame after the cursor movement when first transitioning from no-selection to has-selection. (Bug in 1.69) (#2436) [@Nazg-Gul]

InputText: Simplify read-only code path.

IsWindowHovered() made change which should have no effect in master but fix result of IsWindowHovered(ImGuiHoveredFlags_ChildWindows) over multiple viewport in docking branch. (#2432)

Mention Julia binding in README (#2446) ...

Thank you!

Comments, todo list, remove trailing spaces.

GetMouseDragDelta(): also returns the delta on the mouse button released frame. Verify that mouse positions are valid otherwise returns zero. Removed obsolete comment. Tweaked demo. (#2419)

Examples: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early, and help users understand what they are missing. (#2421)

Version 1.70 WIP

Demo: Custom rendering: Minor sizing issue fix.

Version 1.69, comments, typos

Internals: Fixed Navigation from reaching ImGuiItemFlags_Disabled items (#211) + Examples comments

TabBar: Reworked scrolling policy (when ImGuiTabBarFlags_FittingPolicyScroll is set) to teleport the view when aiming at a tab far away the visible section, and otherwise accelerate the scrolling speed to cap the scrolling time to 0.3 seconds.

TabBar: Fixed Tab tooltip code making drag and drop tooltip disappear during the frame where the drag payload activate a tab.

Examples: GLFW, SDL: Preserve DisplayFramebufferScale when main viewport is minimized. (This is particularly useful for the viewport branch because we are not supporting per-viewport frame-buffer scale. It fixes windows not refreshing when main viewport is minimized.) (#2416)

Fixed Clang and PVS warnings.

InputText: Fixed c779fbb leading to display of the wrong buffer when resizing a buffer. (#2400, #2006, #1443, #1008).

Demo: InputText: Demonstrating use of ImGuiInputTextFlags_CallbackResize. (#2006, #1443, #1008).

Added GetGlyphRangesVietnamese() helper. (#2403)

Internal: Removed unused fields from ImGuiMenuColumns.

Examples: Win32+DirectX: moved helper functions below main.

Fix typos. (#2413)

Don't use const qualified parameters in declarations. ...

This fixes warnings from clang-tidy like this:

    parameter 'v_max' is const-qualified in the function declaration;
    const-qualification of parameters only has an effect in function definitions

Since values (rather than references or pointers) don't need to be
const, they don't need to be marked that way in the function declaration.
