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.

Examples' Says "OpenGL2" vs "OpenGL3" in title bar.

TAB to spaces

Speculative fix for warnings for GCC/Clang

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

Cleanup extra_fonts/ folder

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: Fixed warnings for Clang

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

OpenGL3 example: fix growing of VBO

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

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

OpenGL example: allow resizing window.

OpenGL3 example: fixed mouse handling.

Fix Clang warning with offsetof() macro? Added -Wall in OpenGL 3 example.

Setup Travis CI integration with Clang + -Wall in Makefiles

OpenGL3 example: unregistered mouse callback for mouse click-release faster than frame interval.

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

Examples: OpenGL3: cleaned up to match features of OpenGL2 example

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

Examples: removed LICENSE file from MSVC project.

fixed indentation mix, removed some unused code, updated different callback using the example_opengl code.

added opengl3 sample, mix from @ocornut and @thelinked

Examples: OpenGL: fix accessing libraries via ProjectDir instead of SolutionDir

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.
