Transparent pixels in PNGs were being rendered incorrectly because alpha was ignored. This fix alpha-blends all pixel types with white (255) for proper e-ink display: - Indexed PNGs with tRNS chunk (alpha at palette[768+index]) - RGBA PNGs (alpha from 4th byte) - Gray+Alpha PNGs (alpha from 2nd byte) |

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.
The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").
For example, see the structure of the following example libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
