Chickadee 0.5.0 released

I'm happy to announce that Chickadee 0.5.0 has been released!

Chickadee is a game development toolkit for Guile that is built on top of SDL2 and OpenGL. Chickadee aims to provide all the features that parenthetically inclined game developers need to make 2D and 3D games in Scheme.

New features and improvements:

• New OpenAL-based audio API (see Audio in the manual)
• New API for user-defined shader data types (see Shaders in the manual)
• New, very experimental 3D model loading support for OBJ and glTF formats (see 3D Models in the manual)
• New 3D vector math procedures such as cross product (see Vectors in the manual)
• Improvements to internal GPU state management
• New string->color procedure in the (chickadee render color) module
• New controller-button-pressed? procedure in the (chickadee) module
• New degrees->radians and radians->degrees procedures in (chickadee math) module
• Support for transparent color keying when loading textures
• Tiled map renderer now respects transparent colors for tileset images
• New window manipulation procedures (see Window Manipulation in the manual)
• New Colors section in the manual
• New Input Devices section in the manual

Bug fixes:

• Fixed misuse of streaming vertex buffer in particle system renderer
• Fixed screen not being cleared on frames where nothing is rendered
• Fixed missing bounds check in array-list-ref procedure
