Francesco Abbate 0389bd000a Fix y offset in BakeFontBitmap
Compute Y offset more accurately and the way it is required in
renderer.c.

Instead of returning y offset wrt the baseline position returns it
wrt the top position (the baseline plus the font's ascent).

Francesco Abbate 7c57b1d6ca 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

Francesco Abbate 103336945e 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.

Francesco Abbate 31d7cb5ce0 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.

Francesco Abbate 618078829c 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.

rxi 946c125fd4 Changed `core.redraw` to be set to `true` by default
As the window isn't created until the first frame is drawn this is required to
assure the window is ever shown without relying on the assumption that some
other part of the program would have set this to true
