Added Haddock in the (popup) Aquarium

Sorting of windows for render doesn't do 3 pass stupidly. Made code a little closer to what it should become with a layering system

Fix for using tooltips within popup #126 - will need to rewrite the sorting/layering system shortly.

Renamed internal RenderSortedWindows -> WindowsSortBuffer + cleanup popup closing code

Refactored duplicated code into an inline function & made more readable

Fixed hovering bug introduced in ac2da570 when popup is inactive #126

Popup: clicking on empty space also close popup #126

When a popup window is open it inhibit hovering on other windows #126

Simplified example

Added early version of BeginPopup/EndPopup() #126

Added popup demo code (commented out because I expect to make popup menu proper citizens by next version)

Selectable(const char*, bool) version has bool defaulting to false

Selectable(): not specifying a width default to using max of label width and remaining width

Fixed clipping rectangle's own clipping #177

Renamed IsItemHoveredRectOnly -> IsItemHoveredRect (introduced after previous release)

Avoid negative clipping rectangle when collapsing windows, ImDrawList could still submit data #177

Added a more convenient three parameters version of Begin() which Flags more accessible.

Using SetNextWindowSize() in examples to encourage its use

Fixed new windows auto-fitting bigger than their .ini saved size

OCD normalising function comments not ending with a comma

Fixed SetWindowPos/SetNextWindowPos affectiving size computation (#175)

Fixed new window from having an incorrect content size on their first frame (#175)

Collapsed windows run initial auto-fit to resize the title bar #175 ...

Maybe have side-effects on window contents? Unsure at this point.

Examples: Terser code + added commented out glUseProgram(0( suggestion in OpenGL2 sample.

Merge pull request #174 from adamdmoss/glfwcursor ...

Examples: OpenGL/GLFW: hide system cursor if imgui is soft-rendering cursor

OpenGL/GLFW: hide system cursor if imgui is soft-rendering cursor

ShowTestWindow: missing TreePop() call in Mouse Cursor section.
