Continous Integration for nanvog

problems with the older ubuntu version being used
by github.

Fixed text vanishing when the transform is vertically flipped

Single-byte typo fix

fix for freetype glyph loading

Added a preprocessor definition to disable the use of stb_image

Fixed Signed/Unsigned Comparison Warning

In Visual Studio 17, I get warnings related to these variables:
````
fontstash.h(241): warning C4018: '<': signed/unsigned mismatch
fontstash.h(242): warning C4018: '<': signed/unsigned mismatch
````

Making them unsigned fixes it.

Bind a dummy texture in setUniforms when compiling with emscripten

- nvgTextBreakLines: wordMinX was relative to rowStartX, which caused
problems when rowStartX change on line break, but wordMinX was still
relative to the previous rowStartX
- fixed font size on perf graphs
- made demo to use row minx/maxx instead of row->width
- fixed demo hover distance

Fixes demo’s font sizes.

Fixes the issue that line gap may ruin the text layout.

This commit fixes the demo’s font sizes for the changes in #558, which makes the rendered font size matches what you saw on other native apps. The demo used bigger font sizes than they actually were. This commit deduces the font sizes to match the original demo’s look.

This commit adds `nvgResetFallbackFontsId()` and `nvgResetFallbackFonts()` functions for resetting fallback fonts.

Pass fringe parameter to renderTriangles

Support for loading a certain font face from a font file.

This commit allows loading a certain font face from a font collection file such as TTC.

Fixes the issue that font size is inconsistent.

This commit fixes the issue that font size is inconsistent between different font files. `stb_truetype.h` is also updated to the latest version to support additional font types such as OpenType fonts.
