Scrollbar: Fix for ScrollbarY enable check after ScrollbarX has been enabled. (#1574) Looks like a bug introduced in c36e586.

Scrollbar: Fix ScrollbarX enable test subtracting WindowPadding.x. This has been here since 65a191c (#246) tho at the time it is possible that SizeContents wasn't calculated as evenly. ...

Test: auto-resize with: ImGui::Begin("Test", NULL, ImGuiWindowFlags_HorizontalScrollbar); ImGui::Button("##xxx", ImVec2(500,500)); ImGui::End();

Fixed potential warning (forward declaration and definition didn't match signature. forward declaration only here for consistency)

Fix SetNextWindowContentSize() with 0.0f on Y axis (or SetNextWindowContentWidth()) overwriting the contents size. Broken in eab6333. (#1363)

Fixed old Begin() calling SetNextWindowBgAlpha() with negative values. (#1567, #1568)

Clear BgAlphaCond properly after consuming it. Fixes 9a76fd3 (#1567)

Comments (#1567)

Added SetNextWindowBgAlpha() helper. (#1567) particularly helpul with the marking of the old 5-parameters version of Begin() as obsolete.

Internals: Exposed SetCurrentFont() in imgui_internal.h

Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181)

Internals: Moved unnecessary MovingWindowMoveId field.

Tweaked FAQ.

Comments

Simplified return of ImGui::IsKeyReleased()

ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple context. Also remove the last remaining undesirable dependency on GImGui in imgui_draw.cpp, finishing the work recently done with ImDrawListSharedData. Hurra! (#939)

Horizontal mouse wheel: renamed io.MouseHorizWheel to io.MouseWheelH. Reorganized the code in NewFrame(). Examples: Updated GLFW+GL and SDL+GL accordingly. (#1463)

Merge branch 'tseeker/20171127-feature-horiz-wheel' of https://github.com/tseeker/imgui into tseeker-tseeker/20171127-feature-horiz-wheel ...

Renaming for consistency.

Basic undocumented/unsupported combination of Child+Tooltip. The full feature needs substancially more work but this is enough for simplest cases. (#1345)

Begin: Removed asserts that got in the way of some flags combination. (#1345)

MovingWindow: Track click offset based on root window (undo 514d30d). This should not affect the patch used for #1345 as the RootWindow for Child+Tooltip window points to itself now.

DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559)

Drag and Drop: Increased payload type string to 12 characters instead of 8.(#143)

NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555) + comments.

InputText: Cursor X position not lost when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554)

Internal: DrawData: Tidying, renaming.

Internals: DrawData: We don't need an intermediate layer for popups.

Metrics: Tweaks to hover-window-drawlist to see window bounding box.

Internals: DrawData: Refactored chunks into a ImDrawDataBuilder we can reuse.

Internals: DrawData: renamed fields only (committing separately so that next commit is less nosiy).
