text-freetype2: Increase glyph atlas size

Increase the glyph texture atlas from 2048x2048 to
4096x4096. At larger font sizes the atlas overflows
after caching standard Latin glyphs, causing
cache_glyphs to break early with "Out of space".
Uncached glyphs are then silently skipped in
fill_vertex_buffer, producing missing characters.
