First commit for GM. Added basic framework for the graphics pipeline. All completely untested.
Graphics pipeline is functional. Added Rectangle and Circle primitives.
Made Interpreter able to pipe more than one primitive per entity. Added circle outline drawing (badly). And ran everything through gofmt.
Improved the graphics pipeline to wait for all drawing to finish before flipping the screen. This solves the flickering bug.
Implemented the integer midpoint circle algorithm to make circle drawing better & faster.
Fixed bug in primitive drawing. Was using wrong type of color.
First commit for GAL UTs.
Got graphics testing working! Point & Circle primitives tested.
Fixed bad package capitalization.
Added SDL dependency install to travis.
Tweaking tavis.yml
Nearly working! Adding Go-SDL as a dependency.
Apparnetly installing Go-SDL is really hard.
