Yet Another VGA Monitor Controller

This core is a simple and small VGA controller.

• It drives vga monitors with an 800x600 resolution and 72Hz vertical refresh rate (50MHz pixel clock)
• It displays chars on the screen (each char is 8x16 pixels)
• It has a customizable charset (you can use a simple text editor in order to "visually" customize it)
• It can display a color "waveform"
• It can display a color grid and "cross cursor"
