This commit changes the type of the view size accepted by `nvgRenderFrame()` from `int` to `float` so it matches the type defined in `GLNVGcontext`. This would prevent a framebuffer missing a pixel in final rendering result.
This commit updates font stash to render glyph's bitmap data on demand. This change is intended to fix the issue that `nvgTextBounds()` may return an unreliable result when font atlas is full. This situation usually happens when auto scaling a large font text to fit a small rectangle.
The `fons__getGlyph()` function now accepts a new parameter indicating whether bitmap data is optional, and only `nvgText()` requires it. All of `nvgTextGlyphPositions()`, `nvgTextBreakLines()`, `nvgTextBounds()` and `nvgTextBoxBounds()` functions are changed to work without glyph’s bitmap data.
This commit fixes the bug that `glnvg__renderFill()` allocates unused quad vertices for `GLNVG_CONVEXFILL`, which causes unused vertices uploaded to the GPU.
Besides, the quad for the `GLNVG_FILL` type is changed to drawn by `GL_TRIANGLE_STRIP` instead of `GL_TRIANGLES` so two more vertices can be reduced per quad.
In one of my test case, I need to paste an image to a framebuffer about 5,000 times, and this change would reduce the total number of uploaded vertices from `52,106` to `22,476`. It is good for FPS and battery consumption.
To make the examples link correctly under OS X 12.3, you need to include
<OpenGL/glext.h> in the file. This commit limits what happens by protecting
the include as follows:
#ifdef __APPLE__
# include <OpenGL/glext.h>
#endif
Thus, this should have no effect on non-Apple systems.
To get nanovg to link correctly under OS X 12.3, it needs to be linked against
the Carbon libraries. This was missing in the premake4.lua files. Now fixed.
Previously, the Unicode range of the CJK chractaters only includes Chinese charactaters, Japanese Kanji, and CJK Symbols and Punctuation. The range are used by traditioanl Korean as well. This commit further includes Hiragana and Katakana in Japanese, and Hangul Syllables and Hangul Jamo in Korean to make CJK support more complete.
This commit fixes weird line breaks when rendering CJK (Chinese, Japanese, Korean) characters. Each CJK character is more like a word instead of a letter. This commit fixes the logic of line breaks by introducing a new `NVG_CJK_CHAR` code point type and takes special care for formatting text including CJK characters.
