Docking: Renamed ImGuiDockNodeFlags_PassthruDockspace to ImGuiDockNodeFlags_PassthruCentralNode. + Comments, shallow tweaks. (#2109)

Docking: Tweak and silencing PVS studio static analyzer (back to zero warnings among our selected ones).

Docking: Fixed an issue where windows docked into a node that's part of their dockspace wouldn't recover their order correctly after init. (#2109) ...

(It only worked on floating dock node for the accidental reason that BeginDocked would generally early out on the first frame)

Docking: Wrapping tab bar creation/destroy to make it easier to debug them.

Docking: Fixed crash with ImGuiDockNodeFlags_AutoHideTabBar flag. (#2423, #2109)

Merge branch 'master' into docking ...

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!

Docking: BeginDocked() doesn't need to rely on tab bar data (will allow removing tab bar).

Docking: Preserve existing docked nodes when setting the ImGuiDockNodeFlags_NoDockingInCentralNode flag. (#2423, #2109)

Comments, todo list, remove trailing spaces.

Viewports: Fixed being unable to refocus windows when ConfigViewportsNoTaskBarIcon + ConfigViewportsNoDecoration are enabled. (#2420, #1542) [@PathogenDavid] + comments.

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

Version 1.69, comments, typos

Viewport: DestroyPlatformWindow() skips calling user function if PlatformWindowCreated is set. + Clarified comment about implicit Debug viewport which may be hogging a viewport.

Fixed main viewport not being marked as created, which broke updating the IME input position for the main viewport. ...

This change also removes the logic scattered about that compensated for PlatformWindowCreated being wrong for the main viewport.

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).
