REM =====================================================================
REM  BREAKOUT, for the AKGL BASIC interpreter, using sprite artwork.
REM
REM  Run it with the SDL build:  build-akgl/basic breakout-sprites.bas
REM
REM  Five things about this interpreter shape everything below, and they
REM  are worth knowing before the first line stops making sense.
REM
REM  1. The text layer repaints every row of the window opaque black after
REM     the program's steps have run, so by default anything DRAW or BOX
REM     put on the screen is wiped before it is ever presented. Sprites are
REM     drawn after the text layer, so a sprite is the one thing that is
REM     seen for nothing. Everything drawn here is therefore captured with
REM     SSHAPE and installed as a sprite with SPRSAV -- that is what
REM     sprites 1 and 2 are. They are the screen.
REM
REM     (WINDOW can shrink the text area and hand the rest of the window to
REM     the drawing verbs; it could not be reached from this build when
REM     this was written. It would not help here anyway: a drawing has to
REM     be re-issued every frame and fit inside one batch, and a sprite has
REM     neither constraint.)
REM
REM  2. The host runs 256 source lines and then presents the frame, and a
REM     present throws the drawing buffer away. So all the drawing between
REM     a GRAPHIC 1, 1 and its SSHAPE has to fit inside one of those
REM     batches or the capture comes back half empty. Waiting for TI# to
REM     tick lands us on a batch boundary -- see PACE -- and every draw
REM     routine below is written to stay under about two hundred lines.
REM     Arithmetic is free; only drawing has a deadline. That is why the
REM     lettering is turned into a list of strokes when a number changes
REM     and merely replayed when it is time to draw.
REM
REM  3. There are eight sprites and no more. Two are the screen, five are
REM     the artwork, one is the gem. That is the whole budget, and it is
REM     why the bricks are drawn rather than made of art.
REM
REM  4. There are 128 variables and 64 labels, and this program is close
REM     enough to both that a constant is spelled out rather than named
REM     and several routines that would read better as subroutines are
REM     BEGIN blocks instead.
REM
REM  5. Five things in this dialect did not do what they looked like they
REM     did, and each one cost an evening. THREE OF THEM HAVE SINCE BEEN
REM     FIXED, and are marked below; the shape of this listing is still
REM     theirs, which is why they are still written down:
REM
REM     * **The left operand decides whether an expression is done in
REM       integers or in floats.** 0 - V% throws V%'s fraction away and
REM       0.0 - V% does not; LEVEL# * 0.45 is zero and 0.45 * LEVEL# is
REM       not. This is the dangerous one, because nothing fails -- the
REM       program simply computes something else. It silently quantised
REM       every bounce in this game to whole pixels and silently cancelled
REM       the per-level speed increase. Put the float first, and put the
REM       result somewhere with a % on it.
REM     * A FOR whose bounds are equal does not run its body at all, so
REM       every loop over a list has the one-item case written out beside
REM       it.
REM     * FIXED. A FOR inside a BEGIN block that was SKIPPED did not
REM       survive the RETURN of the routine holding it; the interpreter
REM       lost the GOSUB and reported "RETURN outside the context of
REM       GOSUB". Loops in this program are guarded by GOTO rather than
REM       wrapped in a block, and are left that way because it costs
REM       nothing. TODO.md section 9 item 2.
REM     * FIXED. SSHAPE and GSHAPE ignored the subscript on a string array,
REM       so every element resolved to element zero. The six brick stamps
REM       are six separate scalars for that reason; an array works now.
REM       TODO.md section 9 item 6.
REM     * READ walks one cursor through every DATA item in the file in the
REM       order they were written, no matter which routine is reading.

REM SSHAPE and GSHAPE used to read the leaf they were handed without

REM  Pacing, and the batch boundary it buys
REM
REM  TI# is refreshed from the host's clock once per batch, so the step on
REM  which it changes is the first step of a batch. Spinning here until it
REM  moves is the only way a program in this dialect can find out where a
REM  frame boundary is, and a capture that starts anywhere else risks being
REM  cut in half by a present. Two jiffies is thirty frames a second.
REM
REM  **LASTT# is sampled here rather than carried over from the last
REM  frame**, and that is the whole correctness of it. Carried over, a
REM  frame whose work ran long would find two jiffies already gone and
REM  return on whatever step it happened to be on -- somewhere in the
REM  middle of a batch -- and the capture that followed would come back
REM  holding half of the frame before it. Sampling here means the loop
REM  always sees TI# change under it, and a change is only ever seen on
REM  the first step of a batch.

REM Labels rather than BEGIN blocks here. When this was written it was not
REM a style choice -- a loop inside a block that was skipped left the
REM interpreter with no GOSUB to return from and stopped the program. That
