// This is how grids are handled. On the application side,
|
|
// things are mostly handled this way. Web browsers, etc
|
|
//
|
|
// On the toolkit side, this must be translated into the display
|
|
// code. This is particularly complicated with ncurses but once
|
|
// done in the toolkits, bears fruit in the application code simplicity
|
|
|
|
// NOTE: X numbers horizontally, Y is numbered down. Like in mathematics, EXCEPT Y IS DOWN
|
|
// this is the only sensible way. It's way too confusing to use negative numbers for Y.
|
|
// This is an attempt to make it simple for people to program against this code,
|
|
// then we hide these implementation details in the toolkit plugins
|
|
|
|
// Grid numbering examples (H) or (W,H)
