KAS WGPU

[KAS] shell interface over [wgpu].

Compiling shaders

This library uses GLSL shaders. Pre-compiled SPIR-V modules are distributed so that users do not need a shader compiler.

For working on GLSL shaders, a compiler such as glslc (part of the [shaderc] project) is required. glslc can be installed from Fedora packages, but on other platforms manual installation may be required. Alternatively a web-based tool such as [glslang.js] may be used.

Automatic re-compilation may be enabled by setting e.g. SHADERC=glslc. See build.rs for details.

Optional features

This crate has the following feature flags:

• raster (enabled by default): use [kas-text]'s default backend for glyph rastering (alternatively, specify kas-text/ab_glyph or kas-text/fontdue)
• shaping (enabled by default): use [kas-text]'s default backend (Rustybuzz) for text shaping (alternatively, specify kas-text/harfbuzz or do not use shaping)

Note: at least one of ab_glyph, fontdue is required. If both are enabled, the choice of raster engine is controlled at run-time via theme configuration:

• mode = 0: use ab_glyph
• mode = 1: use ab_glyph and align glyphs to side-bearing
• mode = 2: use fontdue
