Internals: RenderCollapseTriangle() -> RenderTriangle(), takes a ImGuiDir

CollapsingHeader(bool*) variant: fixed for IsItemHovered() to work properly in the nav branch.Basically the close button now has to use ItemAdd() to be navable into, which overwrite the IsItemHovered data. (#600, #787)

Internals: ButtonBehavior: made ImGuiButtonFlags_PressedOnClick and ImGuiButtonFlags_PressedOnDoubleClick set the click offset correctly + hold on g.ActiveId so Held state can be reported. Added ImGuiButtonFlags_NoHoldingActiveId flag to disable the later.

Internals:Helpers: Added ImSwap(int,int), exposed ImStrncpy().

Checkbox: Using checkmark. MenuItem: Tweaked checkmark, thicker.

Begin: Marked 5 parameters version of Begin() as obsolete. Now waiting for a riot to happen!

Begin: Work toward obsoleting the 5-arguments Begin() overload. Internal BeginEx() becomes the normal public Begin() again! (4)

Begin: Work toward obsoleting the 5-arguments Begin() overload. Removed bg_alpha from internal BeginEx(). (3)

Begin: Work toward obsoleting the 5-arguments Begin() overload. Removed size_on_first_use from internal BeginEx(). (2)

Begin: Work toward obsoleting the 5-arguments Begin() overload. (1)

Capture/release window in DX9 implementation ...

This helps a lot when the user drags a slider but carries the cursor offscreen before releasing the button - without the capturing, the slider will "stick" to the mouse cursor even after the button has been released. (This should generally be added to all Windows implementations - I won't mind doing it if you think it's a good idea.)

BeginPopupContextItem() now supports a NULL string identifier and uses the last item ID if available. For interactive items (that have an ID) this works! For non interactive items we assert.

Fix IsItemHovered() issue on child by temporarily reverting 344d48b. This is not the ideal solution. (Fix #1370)

Update README.md

ImDrawList: Fixed a bug in ChannelsMerge() leading to an extraneous draw call being created, which unexpectly led to more dramatic condition but to faulty draw command merging code. (#1172, #1368)

TreeNode: Added ImGuiTreeNodeFlags_FramePadding flag

Internal: ItemAdd(), IsClippedEx(): removed unnecessary indirection for ID parameter

Removed extraneous calls to GetCurrentWindowRead() when we already have a ImGuiContext. Internal RenderXXX functions also don't need to write into the Accessed field at all.

Comments (clarifying whether types are to be considered as flags or regular, non combinable enums)

ColorButton: Reduced bordering artefact that would be particularly visible with opaque Col_FrameBg and FrameRounding enabled.
