* TODO:
* * maybe rename this to 'sprite.hlsl' (draw_rect and stuff would become draw_sprite)
* that way UI & text can have a separate shader (IE: draw_ui_rect, draw_ui_text, etc...)
*
* for tiles - separate shader. maybe upload all tile data in constant buffer, and drawing
* tiles can just be one giant quad (that the fragment shader indexes into)
