- Fixes#140
- Adds a public method to get the current GPU framebuffer texture format (AKA the render texture format).
- This wasn't as difficult as it seemed; the extra API is used by the examples to get the right texture format instead of being hardcoded.
* Update to wgpu 0.9
* Fix validation error in WGSL shader
- This moves the hardcoded vertex positions and texture coordinates to
the vertex buffer.
- Replaces the two-triangle quad to 1 full-screen triangle (fixes#180)
- Rewrites the custom shader example to fix a bug with large surface
textures;
- The input texture size was used for the output texture, causing the
purple rectangle to appear very jumpy on large displays in full screen.
- The `ScalingRenderer` now exposes its clipping rectangle. The custom
shader example uses this for its own clipping rectangle, but it can
also be used for interacting with the border in general.
* Switch to `wgpu::include_wgsl!()`
- This is a nice little simplification.
- Thanks to @JMS55 for the suggestion!
* 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.
* 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.
