The GL_KHR_vulkan_glsl specification states that you cannot do a specialization constant conversion from an integer type to a floating-point type. It states this by omission, as the "Specialization Constant Operations"...

The SPIR-V specification has a number of definitions that deal with implicit derivatives. Let's start with [2.19: Derivatives](https://www.khronos.org/registry/spir-v/specs/unified1/SPIRV.html#_derivatives): > In all cases, derivatives are well defined only if the *derivative...

Add example for `config.ld` to LDoc's documentation

1

LDoc's documentation is pretty decent overall. However, there is one problem: at no point do you show or explain what a `config.ld` file looks like. Perhaps this was a concept...

Cannot add functions to a documented section.

According to the [documentation on Sections](https://stevedonovan.github.io/ldoc/manual/doc.md.html#Sections), a `@section` command has a domain that extends until the next `@section` block (with `@section end` being a special end tag that reverts to...

Useful information about Vulkan extensions can no longer be discovered.

Relatively recent updates to the Vulkan Hardware Database's website make the system decidedly less useful. I find that one of the most useful questions to answer is "what kind of...

Disposition of fragment shader `gl_PrimitiveID` in unusual circumstances

2

The fragment shader definition for `gl_PrimitiveID` is as follows: GLSL 4.6: > The input variable `gl_PrimitiveID` is filled with the value written to the `gl_PrimitiveID` geometry shader output, if a...

GL 4.x allows double-precision uniforms, but the API documentation doesn't expose the `glUniform*d(v)` and `glUniformMatrix*dv` functions.

Consider the statement for a `format` of `GL_RED`: > Each element is a single red component. The GL converts it to floating point and assembles it into an RGBA element...
