Adjust the font's height when creating the bitmap
...
Now the font's height to compute the bitmap is computed correcty but:
- STB truetype takes the pixel height as a float
- AGG takes an integer

Add pixel format to render font in bitmap format
...
The purpose it to add later subpixel by storing the bitmap with RGB
channels to have subpixel LCD coverage information.
The colorization and gamma blending will be done when blitting the glyph
on the destination surface.

Fix LCD font rendering for BGRA32 pixel format
...
Now the sizing of fonts is determined by stb_truetype while the
rendering is done via AGG so they are not aligned.
There seems to be an error also about Y text positioning.

Add meson build configuration
...
Currently the editor will not work if it is not installed.
There is also a caveat about the 'data' directory which is installed
in the bin directory. This may work but does not seem ok because it is
pollution a shared bin directory and the 'data' folder may not be unique
to Lite.
