Added ImGuiCol_TextDisabled

Tweaks

Merge pull request #218 from paperManu/inputNFlags ...

InputFloat2/3/4, InputInt2/3/4: Added extra_flags parameter.

Renamed flags to extra_flags in last commit

BeginPopup() API had to be changed! :( Proper support for stacked popups, leading into menus (wip #126)

Input text flags added to InputFloatN and InputIntN

Example fix PopStyleVar on Vertical Slider to avoid assertion ...

Adding an explicit ImGui::PopStyleVar to avoid assertion in
CheckStacksSize

InputText: make sure Ctrl+V has ONLY the control key pressed (follow up to #214) + tidying

Untabifiy

* make sure letter-key shortcuts have ONLY the control key pressed (fixes bug for AltGr->Ctrl+Alt on windows)

Shutdown() test for g.IO.Fonts not being NULL to allow workarounds in case of using multiple contexts #207

Added style.ScrollbarRounding #212

Merge remote-tracking branch 'origin' into 2015-05-menus

Assert on modifiers stack size mismatch between Begni()/End() pairs #204 ...

Experimenting with this. It's helpful but not happy with the idea of
ImGui asserting on that sort of user error.

Examples: test for tooltip over popup.

Allow stacking popups, not really useful yet (wip #126)

Added ImGuiSetCond_Appearing to test the hidden->visible transition.

MenuItem() draft for popups, with Selected option (wip #126)

Tweak RenderCheckMark()

Added RenderCheckMark() helper following the font size ...

Pretty ugly, not sure what's the right way to solve that automatically,
better shown as an "icon" so it doesn't have to necessarily look like
the font.

Comments (#209)

Fix "Debug" window stealing focus/popup #208 #209 @thevaber

Removed inline marker #210

Removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).

Autofit cancel out one worth of vertical spacing for correct symmetry (group and tooltip already do that)

Popup auto-border doesn't spread to its childs #197

Popup have borders by default #197 attenuated border alpha in default theme

Plot: overlay label clipped within frame when bigger than frame

Popups, Tooltips: fit within display. Hidden during size calculation. Fixed popups flicker when changing size. ...

Big change, needed reorder of Begin(). May trigger new bugs.

Fix for width of child windows with scrollbar (broken 376a6a5)
