Examples: OpenGL3: Tweaks (argh, github ui)

Examples: OpenGL3: Tweaks.

Examples: DirectX11: Removed unnecessary vertices conversion and CUSTOMVERTEX types.

Indexed rendering. Not in main branch because breaks rendering code too much. Will merge in trunk along with more major graphics changes lat

Examples: Formatting #187

set pixel shader and vertex shader to NULL ...

Previous graphic render may use shaders,so set pixel shader and vertex shader to NULL to force use fixed pipeline.

Update README.txt

Examples: OpenGL fixed-pipeline: added glBindTexture(0), via Anton M

Fixed modifier key state setting in GLFW callbacks.

Examples: initializing float + missing comment.

Comments on font loading, fixed commented out paths and added DroidSans in the list

Examples: Terser code + added commented out glUseProgram(0( suggestion in OpenGL2 sample.

OpenGL/GLFW: hide system cursor if imgui is soft-rendering cursor

typo ImGui_ImplGlfwGL3_KeyCallback()

Examples: uses SetNextWindowPos/SetNextWindowSize when applicable

Removed extraneous spaces

opengl3+opengl example: if content window doesn't have focus, tell ImGui we don't have a mouse position. e.g. avoids tooltips popping up in imgui app when you're interacting with a different app window that overlaps it.

Examples: DirectX9: fixed duplicate creation of vertex buffer. Size of static vertex buffer at top of the code.

Examples: Fixed Makefile

Examples: Fixed Makefile

Examples: Fixed Clang warnings in DirectX examples

Examples: MSVC: increase warning level from /W3 to /W4 for OpenGL examples

Examples: MSVC: increase warning level from /W3 to /W4 for DirectX examples

Examples: Fix includes order to avoid conflicts between DXSDK_DIR and Windows SDK

Examples: Added 64-bit projects for MSVC

Examples: Moved GLFW/GL3W to a common libs/ folder

Examples: Updated to GLFW 3.1

Added io.KeyAlt + support in examples apps ...

Currently unused but supported by sample so that more people will have
it set up when menus needs them

Examples: reference implementations honors drawlist user callbacks.

Examples: README direct the user to the opengl_example
