Fixes warning caused by a missing switch/case. (#2382, #2381)

Fix -Wconversion warning (#2379) ...

The warning was caused by implicit conversion from pointer type which
NULL has to non-pointer type, e.g. if ImTextureID is long int

InputText: Fixed deactivated but-last-active InputText instance holding on displaying the last active version of the text and not reflecting change in the source. Fix/amend 2e9a175. [+test]

Fixed uninitialized variable (leading to asserts in the docking branch). (#2376, #2371)

Log/Capture: Fixed extraneous leading carriage return. Fixed an issue when empty string on a new line would not emit a carriage return.

Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute tree depth instead of a relative one. Fixed CollapsingHeader trailing ascii representation being "#" instead of "##". Minor tidying up the of code.

Internal: Log/Capture: Rework to add an internal LogToBuffer() function which is useful for writing automated tests. Clarified logging state by adding an enum.

Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigation to the menu layer. (follow and extend on e.g #369, #370)

TabBar: Added extra mis-usage error recovery. Past the assert, common mis-usage don't lead to hard crashes any more, facilitating integration with scripting languages. (#1651)

TabBar: Fixed a crash when using BeginTabBar() recursively (didn't affect docking). (#2371) ...

Added ImPool::Contains() helper.

Internal: InputText: Tweaks (including a large indentation change, compare ignoring space) to make next commit more digestible.

Internal: InputText: refactor the flow to easily decorrelate rendering of selection vs cursor, which would allow us to render selection on inactive items, and generally makes the code clearer. + Some renaming.

Internal: InputText: Made clipboard copy/cut use its own temporary buffer (like paste) so we can guarantee that TempBuffer if not altered and can be preserved. Renamed TempBufferA to TextA to celebrate this.

Internal: InputText: Renamed is_editable to !is_readonly, Hopefully more explicit. Renamed internal member. Shuffled some code. Added comments, assert (_will_ trigger on !readonly > readonly edge, old bug).

InputText: Fixed an edge case crash that would happen if another widget sharing the same ID is being swapped with an InputText that has yet to be activated.

Internal: InputText: Refactor to clarify access pattern to the InputTextState (we are now accessing via a pointer which can be NULL, shortened its name while we are at it) + added an assert to track an issue that existed already before.

Internal: InputText: Comments. Renamed internal member. Renamed ImGuiStb->ImStb.

Moved binaries to dearimgui.org/binaries

Examples: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if the OpenGL headers/loader happens to define the value. (#2366, #2186)

InputText: Renamed some local variables to clarify code. Should be a no-op functionality wise. TODO items.

InputInt, InputFloat, InputScalar: Fix to keep the label of the +/- buttons centered when style.FramePadding.x is abnormally larger than style.FramePadding.y. Since the buttons are meant to be square (to align with e.g. color button) we always use FramePadding.y. (#2367)

Version 1.69 WIP

Internal: Changed Scrollbar() signature. Using GetScrollbarID() in InputTextMultiline(). ...

Removed multiple semi-colons (#2368)

Updated binaries (now auto-generated by a script! next step would be to slowly transition all this stuff into a public repo)

Examples: VS: Made project paths independant of SolutionDir so they can be built aside from the solution.

Fixed unused argument warning when compiling with IM_ASERT() evaluating to an empty macro.

Version 1.68

Font: Fixed assert when specifying duplicate/overlapping ranges within a same font. (#2353, #2233)

imgui_freeetype: Updated suggested test code.

Examples: Vulkan: Rewrote scissor processing to match other examples more closely. Removed extraneous +1 of scissor extent height.
