Installation

If you're a Rust programmer, lukaj can be installed with cargo. It supports two graphics backends which are enabled/disabled with cargo features.

Feature name	SVG library	2D rendering library
`use-usvg` (default)	resvg	tiny-skia
`use-rsvg`	librsvg	cairo

Depending on the operating system and selected feature set, lukaj will require additional development libraries.

When using only default use-usvg feature:

$ sudo apt-get install libsdl2-dev
$ cargo install lukaj

When using additional use-rsvg feature:

$ sudo apt-get install build-essential libcairo2-dev libgdk-pixbuf-2.0-dev \
    libglib2.0-dev libpango1.0-dev libsdl2-dev libxml2-dev
$ cargo install lukaj --feature user-rsvg

Install MSYS2 and run from it's terminal run:

For default use-usvg feature:
```
$ pacman -S mingw-w64-x86_64-SDL2
```

For additional use-rsvg feature:

$ pacman -S mingw-w64-x86_64-gtk4 mingw-w64-x86_64-gettext \
    mingw-w64-x86_64-libxml2 mingw-w64-x86_64-pkgconf \
    mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2

Add mingw binaries path (C:\msys64\mingw64\bin) to system Path

Change default rust toolchain to stable-gnu

rustup toolchain install stable-gnu
rustup default stable-gnu

Run cargo install command
- For default feature only:
```
$ cargo install lukaj
```
- For additional use-rsvg feature:
```
