* Validate width and height inputs
- Fixes#157
* Add window size check to `imgui-winit` demo
- There is really nothing better that can be done in this case.
- The surface, buffer, and world sizes must all be non-zero.
- A zero-length surface would (previously) panic in `wgpu`.
- A zero-length buffer would panic with the new assertions.
- A zero-length world would cause a divide-by-zero panic when drawing.
- Was originally resizing the pixel buffer with `PhysicalSize` units, which is definitely incorrect. (The pixel buffer is created with `LogicalSize` units.)
- Updated the World struct to retain its own size information.
- The dependencies are a mess!
- Had to fork `imgui-wgpu`, which sits between 0.12 and 0.13 (has support for `winit` 0.24, but not `wgpu` 0.7)
- This is a temporary fix for CI, until https://github.com/Yatekii/imgui-wgpu-rs/pull/44 is merged and a new release of `imgui-wgpu` is out
- The WIP `wgpu` 0.7 update in https://github.com/parasyte/pixels/pull/134 will be needed for `imgui-wgpu` 0.14
- Update MSRV for `imgui` 0.7
* Add Dear ImGui example
- Closes#90
* Change argument order to match `render_with`
* Remove unnecessary borrow
* Refactor error messages
* Add a space
* Refactor Gui field privacy
* Add a menu bar and allow the about window to be closed
- The local bool is necessary because the menu bar closures are not allowed to borrow `self` for mutable access while `imgui::Ui<'ui>` is alive.
- The token-based menu bar lifetime is even more verbose than this.
* WIP: Render API v2
* Fix doctests
* Expose all of PixelsContext (#110)
* Fix ScalingRenderer::new() taking &mut Device
* Replace getters with direct access to &mut PixelsContext
* Fix wrong reference type
* Fix unneeded mut
* Remove unnecessary mutable borrow, resurrect the shorter getter methods
* Initial port to wgpu master (0.6)
Surface creation is broken (see examples)
Does not support compressed textures
* Fix SurfaceTexture and examples
* Add support for compressed texture formats
* resize doesn't need mutability
* Update documentation
* Update wgpu
* Prepare release
* Goodbye Travis! Thanks for all the fish

* Add a method to convert cursor coords to pixel coords
* Add method `window_pos_to_pixel` to Pixels struct
* Converts cursor / window physical coordinates to pixel coords
* Fix formatting
* Return result rather than clamping pixel coordinates
* Use transformation matrices to convert from cursor coord to pixel
* Adds a struct ScalingMatrix that manages the creation and usage
of the transformation matrix used in the renderer.
* Added an inverse function on ScalingMatrix - 4x4 matrix inverse
(This should probably use a library, but it doesn't seem worth
adding a dependancy for one function)
* Optimize matrix multiplication for cursor position calculation
* Use ultraviolet for matrix and vector math
* Add suggested changes
This keeps the split between usize and isize
This also changes the input cursor position to f32, because it was
immediately cast to an f32 for the transformations.
* Move all examples to individual crates
* CI: Add libsdl2
* Use Ubuntu bionic for updated libsdl; 2.0.8
* Clippy
* libudev-dev is a dependency of libsdl2-dev
* Clippy
* Remove unnecessary dev-dependency
* `winit` is actually used in unit tests
* Fix a typo
* Move `simple-invaders` crate
* Add a conways game of life example
* Rustfmt conway example
* Respond to review feedback (p_width/p_height)
* Use line_drawing instead of manual bresenham
* Optimize count_neibs
* Remove inline(never) leftover from when profiling
* Bring back wrapping behavior (without regressing perf)
* Fix missing bounds check
- This works because `wgpu` is a dependency for `pixels`
- But this example should be demonstrating how to ony depend on `pixels` ... And whatever windowing system and event-loop you might want.
* Refactor window creation and size handling
* Require pixel aspect ratio to be > 0
* Fix screen scaling when window is resized
- Ensure the screen retains its correct pixel aspect ratio
- Updated public API on `RenderPass` ... this will continue to be unstable until the initial release
- Add build instructions for the internal shaders
