Add an UI element to report WebGL shader compilation errors Use-case 1) when user edits the shader in the inspector, the syntax errors are not visible Use-case 2) when the user has a syntax error in the original source, there's no easy way to discover this The use-case 1 might be of higher priority for this bug In bug 241010 we removed the ad-hoc prints to console when shader compilation fails.
