RenderRectFilledRangeH() can't use cheap acosf() approximation for now. (#1296)

ProgressBar() fixed rendering when straddling rounded area. (#1296)

Added overcomplicated RenderRectFilledRangeH() to fix rounded progress bar, which will also help for range widgets and perhaps sliders grabs over rounded areas. (#1296, #76)

ImDrawList: Minor renaming

ImSwap() helper.

imDrawList: PathArcTo() returns when passed zero radius.

ImDrawList: Minor tidying up.

Internals: Renamed some ImGuiCorner enums.

ParseFormatPrecision() returns -1 for scientific noation 'e'/'E', RoundScalar() doesn't alter those.

Added Go binding link

Updated copyright date for 2017, updated Gallery link

Internals: Split some code out of NewFrame() into an Initialize() function.

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.

Fixed compilation with IMGUI_DISABLE_OBSOLETE_FUNCTIONS defined

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.
