Windows: setup a default handler for ImeSetInputScreenPosFn so IME (Japanese/Chinese) inputs are positioned correctly. ...

User need to set io.ImeWindowHandle

Renamed ImGuiSetCondition_*** to ImGuiSetCond_*** and ImGuiCondition_FirstUseThisSession to ImGuiCond_Once

Examples: DirectX examples applications all have a Console for debugging.

Calculate frame-rate for the user, as a purely luxurious feature ...

..and to reduce sample code size a little.

Minor formatting tweaks, comments

Examples: DirectX11: fixed handling of unicode character inputs.

Examples: DirectX11: increasing vertex buffer size (would really need a dynamic buffer size) ...

+ Delete unused code

Examples: changed default background color.

Examples: more comments on loading fonts.

Renamed FontAtlas to Fonts. Further cleanup/comments.

ImFontAtlas allows loading multiple fonts into same texture. Revamped new init API for 1.30

Removed PixelCenterOffset, uncesssary

Examples: DirectX11: use linear sampler to be in sync with other examples.

Merge remote-tracking branch 'upstream/master' into 2015-01-truetype ...

Conflicts:
	imgui.cpp
	imgui.h

Examples: Added a color slider for the background color + tweak first example use of button.s

ImFont::GetTextureData API allow to retrieve 8/32 bits data + lazily load defaults font ...

Examples: OpenGL3 and DirectX11 back to using 32-bits texture solely for
ease of integration.

Mde it optional to new() io.Font - however it stills needs to be loaded.

TAB to spaces

Examples: all supports TextureID in renderer, added LoadFontTexture() function.

Loading TTF file with stb_truetype. Broke setup API slightly. Font baked, packed with space for custom data. Embeds compressed ProggyClean.

Fixed DirectX11 example.

Examples: Added STB_IMAGE_STATIC in examples to avoid conflicting implementation. Relate to #109

New and better Set[Next]Window(Pos|Size|Collapsed) API. ...

Removed rarely useful SetNewWindowDefaultPos() in favor of new API.

Examples: DirectX11: moved shader to be close to its usage location,

Examples: adding title to the top of each examples. Cleaning up file headers.

DirectX11 example: fixed projection matrix offset.

DirectX9/DirectX11 example: fixed window initially showing an hourglass cursor.

Example apps: accumulate mouse wheel to accodomate for slow framerate.

DirectX11 example: further tweaks/massaging (-15 lines). Syncing example.

Tab->Spaces :( visual studio can't even be trusted for that, oh thanks.
