Subject: Add an option to indent the glsl code in the shader viewer.
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=ab347b0a2d3d70a4524494cf14130cf3ed10947e;p=apitrace

Add an option to indent the glsl code in the shader viewer.

Requires 'astyle' but works very well and makes reading wonky
shaders a /lot/ easier.
