resolve TODOs regarding input.h

a) mouse position must be integer, because it can be negative (though rarely)
b) we should not trade "access complexity" for space in the scancodes array

 layout(location = 0) in vec2 in_pos;
 layout(location = 1) in vec2 in_uv;
 out vec2 uvcoord;
 uniform mat4 projection;
 uniform mat4 view;
 uniform mat4 model;
 void main(void) {
     vec4 pos = projection*view*model*vec4(in_pos.xy, 0.0, 1.0);
     gl_Position = pos;
     uvcoord = in_uv;
 }
