* Added clear_atlas_region_caches & clear_shape_cache to VEFontCache (Used on hot-reload by the pototype's font provider)
* Made glyph_draw's over_sample a vec2 for initialization (incase user wants to do some float value multiple of 4x4)
* ADVANCE_SNAP_SMALLFONT_SIZE made a runtime option: Shaper_Context.adv_snap_small_font_threshold
* Large imporvement to text hinting and general rendering of text
