15d77c648d Speed up loading of background image 
Use a persistent cache of RGBA data. Also as a free bonus, support more
image formats for the background image.

248301f8b3 Cleanup a bunch of shader infrastructure 
1) No longer us glScissor. It's an awful API and is not available in
   Vulkan. Instead the graphics drawing code ensures the graphic is
   drawn within the current viewport

2) Use generated code to automatically get the locations of uniforms
   from shaders. Greatly simplifies adding new uniforms to a shader.

3) Dont use a VAO for loading graphics vertices. Greatly simplifies
   a bunch of book keeping code.

d63eeada73 Image placement using Unicode placeholders 
This commit introduces the Unicode placeholder image placement method.
In particular:
- Virtual placements can be created by passing `U=1` in a put command.
- Images with virtual placements can be displayed using the placeholder
  character `U+10EEEE` with diacritics indicating rows and columns.
- The image ID is indicated by the foreground color of the placeholder.
  Additionally, the most significant byte of the ID can be specified via
  the third diacritic.
- Underline color can be optionally used to specify the placement ID.
- A bug was fixed, which caused incomplete image removal when it was
  overwritten by another image with the same ID.

f3b9ff5f9f Use datatype monotonic_t instead of double to keep track of time 
The time is stored in a signed 64 bit integer with nanosecond accuracy. This eliminates the possibility of floating-point inaccuracies.
`monotonic_t` can currently hold values large enough to work correctly for more than 200 years into the future.
Using a typedef instead of directly using `int64_t` everywhere will also allow easily changing the datatype in the future should the need arise for more precise or bigger time values.
