[aiekick]

To be saved as global settings struct

• Param Scale
• Glyph Translate / Glyph Auto Frame
• Glyph Size / Glyph Auto Size
• Tex Size
• Glyph Padding
• Sdf Algo
• Sdf Range
• Invert Y

i there is no conf on a new font file, we keep the last defined params.
maybe a give a button, with a dialog for let choice to the user to have last or new params

in the shader conf :

• buffer iterations count
