　 SKIA graphics and acceleration based on Vulkan GPU

The OpenGL back end used on Windows for the interface was replaced with Skia and Vulkan. SKIA is an open source 2D graphics library that provides a common API that supports working on various hardware and software platforms. It can be used to draw text, shapes and images. Vulkan is a new generation of graphics and computing APIs, which has the ability to access modern GPUs with high efficiency and cross -platform access to modern GPUs.

This model is to ensure that users of different versions of Microsoft Office can work together, so that the documents created by the old version of Office also maintain the same display effect when opening in the future version of Office.

For XLSX files, the export of the workbar name is greater than 31 characters to XLSX format. In addition, the check box can also export to the XLSX format, and solve the exported XLSX file If it contains the shape, the problem of "invalid content errors" will occur when it is turned on.
