Fix distorted text with subpixel matrix translation
We would pixel-align native text *before* applying the
model-view matrix, which would cause GL_NEAREST artifacts to
show up when the text was positioned at a subpixel offset in
some cases. Instead, we pixel-align the coordinates after mapping
them to the view frustum, but before applying the projection to the
screen.
To make it easier to modify the buffer layout for the shaders the
next time, this also adds some constants for offsets.
[ChangeLog][Text] Fixed an issue where text using NativeRendering
would look slightly skewed if it was inside a parent that had
been positioned at a subpixel offset.
