- We just add to a frame of quads which the renderer deals with in gfx_update - draw_quad, draw_rect, draw_rect_rotated - Currently just implemented with legacy opengl, so we can't do custom shading - Added third party code from lodepng so we can load pngs without any other dependencies (no C includes) - ALLOCATOR_REALLOCATE - Basic Vector2, Vector3, Vector4 stuff, and some math utilities - Added <math.h> dependency for now. - Graphics renderer frontend layer - Naive get_random() implementation
