[renderer] Reduce glyph pixel area padding from 2x to 1.2x

Browse source 
With the improved atlas allocation, 2x is no longer needed and 1.2x
seems to be sufficient. Most importantly, it reduced the texture for
amiri-regular.ttf at 72 pix height from 8x to 4x (the staging buffer
isn't big enough for 8k textures).
