Fixed not being able to move a window by clicking on one of its child window (#1337, #635), broken by https://github.com/ocornut/imgui/commit/313d388bba42e0634a02b976dcdbae238d25eddc

Removed extraneous ImGui:: prefixes. Declared ColorEditOptionsPopup in imgui_internals.h. Tweaked internal signatures.

ImFontAtlas: Fixed calling Clear() and rebuilding (broken in 3fe2ecf) thanks @pdoane @mikesart

Combo: Cleaned up, removed unnecessary code (looks like this part went untouched for a long time!).

ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas / and map them as font glyphs

Minor comments

ImFont: Renamed (supposedly internal) fields (e.g. XAdvance to AdvanceX). Custom text renderers might be affected if they didn't use the GetCharAdvance() helper function.

ImFont: Renamed ImFont::Glyph to ImFontGlyph (for consistency and so ImFontAtlas types can use it without ordering half of the file). Left a redirection type.

ImFontAtlas: Refactored internals API to 1) avoid building lookup table multiple times for merged fonts + 2) allow the mapping of custom icons inside fonts (wip, uncommited)

ImFontAtlas: Comments and minor reorganization of declaration in header file.

ImFont: Split some building code into a AddGlyph() helper (that custom rect code and imgui_freetype can use)

Separator(): output vertical separator when used in horizontal layout mode, so it works in menu bars.

Horizontal layout does the minimum job to be usable internally - not exposed (#97)

Comments, debug code (commented), todo list

Fix static misusage error with decent compilers. Error introduced in 4b82759

WantCaptureMouse: Tweaked logic so WantCaptureMouse can stay false when e.g. hovering over void while an InputText() is active. (#621)

Exposed PushMultiItemsWidths() to imgui_internal.h

Merge pull request #1113 from Urmeli0815/ImGuiSelectableFlags_MenuItem ...

MenuItem: only activate on Release, not on Click (nb: and not on ClickRelease to allow opening menu and selecting something with a single click. Windows seems to behave the same, allowing to click and hold to e.g. Open then move cursor, release on Save and save gets activated)

Begin: Fixed auto-fit calculation code that predict the presence of ascrollbar so it works in the case size constraints are used. I actually don't need this fix now, but earlier experiment with BeginCombo() required this fix.

Begin: Moving some code into a CalcSizeAutoFit() function.

BeginCombo(): rework internals a little to make it easier to provide custom combo-like elements relying in BeginCombo(). ...

BeginPopupEx() doesn't enforce AlwaysAutoResize flag anymore.

Demo: Fixed overlay demo keeps resizing (in case, e.g.: font changes)

SetNextWindowPos: added a ImVec2 pivot parameter for positioning a given a center, bottom-right position, etc. As a generalization of SetNextWindowPosCenter() which is now obsolete. This will be useful for combo-like popups as well. ...

Demo: Simple-overlay window uses the SetWindowPos pivot to select a corner to position itself at.

Begin(): Minor tidying up of flow

Window: Tweaked ApplySizeFullWithConstraint() -> CalcSizeFullWithConstraint() so it can be used without side-effect

Popups: Exposing a little more of popups internals in imgui_internals.h

Examples: DirectX11: allow creating device with feature level 10 sinec we don't really need much for that example. (#1333)
