* graphics: blend: Add proper <blend-mode> data type.David Thompson2021-03-145-47/+120
| | | | No more symbols. Hooray!
* graphics: Rewrite with-graphics-state to use state specs.David Thompson2021-03-1418-67/+123
| | | | | | | | | | | | | | | | 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
|
* graphics: path: Include blend module.David Thompson2021-03-131-0/+1
| | | | | Without it, setting the blend mode fails unless the module has been included by something else.

|
* 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.
* graphics: path: Fix bug where blend mode wasn't set during fills.David Thompson2020-11-191-0/+1

| | | | Hopefully, that is.

|
* graphics: buffer: Fix silly error in render-vertices/instanced.David Thompson2020-11-181-1/+1
| | | | | Used 'when' when I meant to use 'if' and therefore both branches of what should have been a conditional were executed. :(
* math: quaternion: Remove calls to deleted square procedure.David Thompson2020-11-181-5/+5
| | | | Oops.

|
* math: rect: Move functional procedures after the imperative ones.David Thompson2020-10-151-56/+61
| | | | | The functional procedures weren't working because of a quirk with Guile's handling of the top level.
