Tidying up - ImRect doesn't use ImVec2 operators (so we can expose it later)

Tidying up - ShowUserGuide, ShowStyleEditor only uses public calls

Tidying up - renamed a few internal functions

Tidying up - moved ImFontAtlas glyph ranges helpers outside of ImFont block

Minor tidying up

Version number 1.42 wip + todo list entries

Fixing 64-bit compilation warning caused by implicit size_t->int cast

Demo: satisfying buffer size

Version 1.41

Carriage return in demo tooltip

Fix for correctness and allow non-auto resized modals to have window minimum size applied - hopefully no-side effects (#249)

AutoFit can be triggered on each axis separately via SetNextWindowSize() (mentioned in #249)

Minor construction fix (-1.0 is correct "disabled" value for TextWrapPos, didn't have any incidence anyway)

Fixed SetNextWindowPosCenter() being processed too early for windows that are still measuring their size (for #249)

Added SetNextWindowPosCenter() (#249)

BeginPopupModal() default to NoCollapse for modal windows (#249)

Modal windows centered when appearing (#249)

Added GetGlyphRangesCyrillic() helper (#237)

Added stacked modal windows example (#249)

Added modal dialog example (#249)
