SetKeyboardFocusHere() added assert to prevent passing values smaller than -1 as we may have to outlaw them (I think nobody was using that)

Styles: Added ImGuiStyle::ScaleAllSizes(float) helper to make it easier to have application transition to e.g. High DPI with a matching style.

Added VerticalSeparator() entry point in imgui_internal. Seperator() in an horizontal layout context still does that.

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

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: 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)

Comments, debug code (commented), todo list

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

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.

Added io.WantMoveMouse flags from Nav branch so Examples/Binding can already implement it. (#787)

Merge branch 'master' into styles

Internals: moved ButtonRepeat and AllowKeyboardFocus bools/stacks to a generic ItemFlags stack. Merged from Navigation branch.

Added IsWindowAppearing().

Removed 2 obsolete redirection functions (obsoleted 26+ months ago).

Added GetKeyPressedAmount() (from Nav branch) to be able to measure fast repeat rate accurately. Added internal CalcTypematicPressedRepeatAmount() function.

Merge various minor things (supposedly harmless) from Navigation branch into Master to reduce differences. (#787)

Added IsMousePosValid() helper.

ImFontConfig: Added RasterizerMultiply option to alter the brightness of individual fonts at rasterization time, which may help increasing readability for some. Added RasterizerFlags for custom rasterizer flags (aka imgui_freetype)

ImFontConfig: Comments, const.

IO: io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we'll now accept negative mouse coordinates.

Marked all fmt + va_list functions with format attribute so GCC/Clang can warn about them. Not ignoring -Wsuggest-attribute=format anymore for GCC/Clang.

Version 1.52 WIP

Version 1.51

Renamed IsItemHoveredRect() to IsItemRectHovered(). Renamed IsMouseHoveringWindow() to IsWindowRectHovered() - follow up to previous commit 6be7d49 merged from Nav.

Style: Added obsolete redirects for ImGuiCol_Columns*** fields. (ref 648f75b)

Merge part of 88c1966 from Nav branch. Renamed IsMouseHoveringAnyWindow() -> IsAnyWindowHovered(), IsMouseHoveringWindow() -> IsWindowHoveredRect() for consistency. Kept inline rediection function.
