Added PushId() GetId() variants that takes string range to avoid user making unnecessary copies

DragFloat() added power parameter for logarithmic drag on both side of zero #180

DragFloat() latch value internally, allows finer control, honor precision settings, slow step with integer works #180

DragInt() step given as float to allow finer control of speed #180

DragFloat() latch value internally, allows finer control, honor precision settings, slow step with integer works #180

Added ImFontAtlas::AddFontFromCompressedTTF() helper + binary_to_compressed_c.cpp tool

ImDrawList: bits of renaming.

Renamed io.MetricsVertices to io.MetricsRenderVertices

Spacing

ImDrawList: internal refactoring toward a following commit for indexed rendering.

Renamed AddArcFast() parameter 'tris' to 'filled'

Revert AddArcFast()->AddArc(), removed modulo from function 200d348

Renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API, and changed 2*PI range from 0..12 to 0..16

fix initialising ints with float literals

Added ShowMetricsWindow()

Added IO.MetricsVertices counter

Allow SetWindowFocus(NULL) to remove focus

Comments

DragFloat() comment examples, not ready for prime-time #180

DragFloat(): passing min>=max (e.g. 0.0f) for range makes the drag unbound #180, removed extra APIs

Added DragFloat(), DragInt() work in progress #180

Comments and organization of imgui.h

Delete font clear pointer in ImGui state to get a clear crasah instead of a dangling pointer. #181

ImVec2/ImVec4 no-parameters constructs init to 0.0f. Saner. Couldn't measure perf differences in a simple stress test compiled in Debug mode

Version number 1.38 WIP

Changed new ImDrawList::AddLine() half_thickness to hickness, just in time for release

Version number 1.37

Removed bool return value from BegniPopup() at the moment, it is meaningless. Tidying up.

Added early version of BeginPopup/EndPopup() #126

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