- Font loading - Measuring for formatting & justification - Utf8 Glyph walking - Commented example in oogabooga/examples/text_rendering.c - Small 2D renderer refactor - Pass 8-bit integers "type" and "sampler_index" to shader - Sample texture differently depending on "type" (text or regular quad) - Sample with nearest/linear min/mag depending on sampler_index - Set min/mag filtering in Draw_Quad - Images are now created and deleted directly with gfx calls rather than deferring it for gfx_update. - We can now set image sub data with gfx_set_image_data() - Images are no longer hard coded to 4 channels - Utf8 utility: - utf8_to_utf32(): convert utf8 bytes to a single u32 codepoint - next_utf8(): Convert first utf8 character in a string to a u32 codepoint and advance the passed string to the next unicode - Renamed m4_multiply -> m4_mul for consistency - Refactored os window to be DPI aware (scaled_width vs pixel_width) - in minimal example, renamed hammer_xform -> rect_xform
