1. There is a Katex parsing error on this page (https://www.khronos.org/registry/OpenVX/specs/1.3/html/OpenVX_Specification_1_3.html)

ParseError: KaTeX parse error: Expected '}', got '\root' at position 10: \frac{1}{\̲r̲o̲o̲t̲ 4 \of {2}}

2. On this page in the 1.3 Provisional Specification under 1.1 Purpose, this link is broken: https://www.khronos.org/registry/OpenVX/specs/1.3/OpenVX_Specification_1_3.html

3. Based on issue #38 I realize this might not get fixed, but posting for completeness. The following URLs have missing images:
