* graphics: blend: Add proper <blend-mode> data type.David Thompson2021-03-146-66/+202
| | | | No more symbols. Hooray!
* graphics: Rewrite with-graphics-state to use state specs.David Thompson2021-03-1419-68/+124
| | | | | | | | | | | | | | | | Treating the names inside the let-like form as just symbols caused numerous bugs where a program would crash because it was trying to set graphics state that was never defined due to the relevant module never being imported. By changing with-graphics-state to require passing in the <graphics-state-spec> object, much like how parameterize works with parameter objects, it completely eliminates this type of bug. If the module containing the spec variable isn't imported, there will be an undefined variable error thrown early on. Additionally, graphics state objects needed to have a stack added to them to track previous values so that with-graphics-state could restore them later. The old trick of using let to stash the previous values no longer worked with the new macro implementation.
* graphics: engine: Improve error message when graphics state is undefined.David Thompson2021-03-131-1/+8

* Revert "Do not auto-compile example files before running them."David Thompson2020-11-191-1/+1
| | | | | | | This reverts commit 0a13a8e9760091031986fe3a429645113dd038b1. This was causing examples to perform horribly due to the compiler not being active. The sprite batch example in particular took a huge hit.
* graphics: Add polygon and cull face modes to render context.David Thompson2020-11-196-13/+153
|
* graphics: path: Allow model-view matrix to be applied to rendered path.David Thompson2020-11-191-8/+17
| | | | | | | | | Every other type of rendering operation supports this, so paths should be no different. This type of transformation, unlike a transformation applied at the canvas or painter level, can cause a non-smooth output the matrix scales the result since it's transforming the geometry as-is rather than building new geometry with all path points transformed.
* Update game controller database file.David Thompson2020-11-191-3/+17
