ShowTestWindow(): more examples of SameLine() usage

ShowTestWindow(): added vertical sliders examples, tweaks.

Changed mentions of 'box' to be 'rect'

Changed remaining mentions of 'aabb' to be 'rect'

Renamed internal type ImGuiAabb to ImRect

Added BeginGroup() / EndGroup() layout tools (#160)

Added GetItemRectSize(). Renamed GetItemRectMin()/GetItemRectMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHovering

Button() doesn't add frame padding an explicit size

Maintaining DC.CursorMaxPos instead of SizeContentsCurrent, simpler, faster and easier to understand.

Various fixes related to vertical alignment of text after widget of various sizes. Added demos. Toward #160 ...

Also fixed LabelText() height.

Moved text vertical centering out of ItemSize() for the moment, in TextUnformatted() it's only user

Internal tweaks

Changed default Border and Column border colors to be most subtle, less MS-DOS

Speculative warning fix

Examples: uses SetNextWindowPos/SetNextWindowSize when applicable

Removed extraneous spaces

Merge pull request #159 from adamdmoss/master ...

Examples: OpenGL: if content window doesn't have focus, tell ImGui we don't have a mouse position.

opengl3+opengl example: if content window doesn't have focus, tell ImGui we don't have a mouse position. e.g. avoids tooltips popping up in imgui app when you're interacting with a different app window that overlaps it.

Examples: DirectX9: fixed duplicate creation of vertex buffer. Size of static vertex buffer at top of the code.

Moved static buffers into state ...

No recursion in any of those functions. Tho keeping a lock api may be
preferable?

Moved static buffer into state

TreeNodeV() early out if SkipItems is set (avoid formatting string only to be discarded later)

Added InputInt2(), InputInt3(), InputInt4()

ShowTestWindow() using Unindent() / Indent() instead of an explicit TreePop

Added Indent(), Unindent()

Renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing

ShowTestWindow() added multi-components sliders in a sub-node ...

+ right align all widgets
