Use unorm shorts for texture coordinates when rendering text.
There are a couple of reasons for this:
- Vulkan does not guarantee conversions from integral vertex attributes
to floating point shader variables
- This may be faster and more precise on some platforms, as it avoids
the aforementioned conversion and changes a multiply by a very small
value to a multiply by a medium-sized value.
