dear-imgui-wgpu 0.7.0

# dear-imgui-wgpu


WGPU renderer for Dear ImGui.

## Quick Start


```rust
use dear_imgui_rs::Context;
use dear_imgui_wgpu::{WgpuRenderer, WgpuInitInfo, GammaMode};

// device, queue, surface_format prepared ahead
let mut renderer = WgpuRenderer::new(WgpuInitInfo::new(device, queue, surface_format), &mut imgui)?;

// Optional: unify gamma policy across backends
renderer.set_gamma_mode(GammaMode::Auto); // Auto | Linear | Gamma22

// per-frame
renderer.render_draw_data(&imgui.render(), &mut render_pass)?;
```

## What You Get


- ImGui v1.92 texture system integration (create/update/destroy)
- Multi-frame buffering and device-object management
- Format-aware or user-controlled gamma (see below)

## sRGB / Gamma


- Default `GammaMode::Auto`: picks `gamma=2.2` for sRGB targets and `1.0` for linear targets.
- You can force `Linear` (1.0) or `Gamma22` (2.2).
- Pair this with your swapchain format to avoid double correction.

## Compatibility


| Item            | Version |
|-----------------|---------|
| Crate           | 0.7.x   |
| dear-imgui-rs   | 0.7.x   |
| wgpu            | 27      |

## Notes


- Targets native and Web (with `webgl`/`webgpu` features mapped to wgpu features).
- External dependency updates (wgpu) may require coordinated version bumps.

## Features


- Default: no extra features required for native builds
- `webgl`: forwards to `wgpu/webgl` (WASM + WebGL)
- `webgpu`: forwards to `wgpu/webgpu` (WASM + WebGPU)

Pick exactly one of `webgl` or `webgpu` for browser targets; for native leave both off.
