gray: finalize the gray engine API
* Define dgray() to replace gray_start() and gray_stop()
* Introduce a mechanism to override the d*() functions rather than using
another set of functions, namely g*(). Gray rendering should now be
done with d*() (a compatibility macro for g*() is available until v2.1).
* Gray engine now reserves TMU0 at the start of the add-in to prevent
surprises if timers are exhausted, so it nevers fails to start
* Replace other gray engine functions with dgray_*()
* More general rendering functions (in render/) to lessen the burden of
porting them to the gray engine. As a consequence, dtext_opt(),
dprint_opt() and drect_border() are now available in the gray engine,
which was an omission from 230b796.
* Allow C_NONE in more functions, mainly on fx-CG 50
* Remove the now-unused dupdate_noint()

|

This function makes the contents of the VRAM visible on the screen. It is
|
||||
the equivalent of Bdisp_PutDisp_DD() in most situations.
|
||||
|
||||
On fx-9860G, this function also manages the gray engine settings. When the
|
||||
gray engine is stopped, it pushes the contents of the VRAM to screen, and
|
||||
when it is on, it swaps buffer and lets the engine's timer push the VRAMs to
|
||||
screen when suitable. To make the transition between the two modes smooth,
|
||||
dgray() does not enable the gray engine immediately; instead the first call
|
||||
to update() after dgray() switches the gray engine on and off.
|
||||
|
||||
On fx-CG 50, because rendering is slow and sending data to screen is also
|
||||
slow, a special mechanism known as triple buffering is implemented. Two
|
||||
VRAMs are allocated, and frames are alternately rendered on each VRAM. When
|
||||
dupdate() is called to push one of the VRAMs to screen, it starts the DMA
|
||||
(which performs the push in the background) and immediately returns after
|
||||
switching to the other VRAM so that the user can draw during the push.
|
||||
|
||||
The transfer from the DMA to the screen lasts about 10 ms if memory is
|
||||
available every cycle. Each access to the memory delays the transfer by a
|
||||
bit, so to fully use the available time, try to run AIs, physics or other
|
||||
calculation-intensive code rather than using the VRAM.
|
||||
|
||||
Typical running time without overclock:
|
||||

|

The control of the screen is transferred to the engine; you should not use

dupdate() after this function, only gupdate().
|
||||
This function configures the display module to work with or without the gray
|
||||
engine. When the mode is set to DGRAY_ON, all rendering functions are
|
||||
replaced to use gray rendering, and gray frames will start being displayed
|
||||
after the next dupdate(). To transition from monochrome rendering to gray
|
||||
rendering, you must first call dgray(DGRAY_ON), then draw your first gray
|
||||
frame from scratch, then call dupdate().
|
||||
|
||||
The engine uses timer number GRAY_TIMER (equal to 0 by default) to run. If
|
||||
the timer is unavailable, this function will fail. Otherwise, the gray
|
||||
engine is started and any attempt to use timer 0 while it is running will be
|
||||
denied by the timer module. */
|
||||
void gray_start(void);
|
||||
Similarly, when the mode is DGRAY_OFF, all rendering functions are replaced
|
||||
to use monochrome rendering, and the next frame sent with dupdate() will
|
||||
stop the gray engine on the display. To transition back to monochrome
|
||||
rendering, call dgray(DGRAY_OFF), draw your first monochrome frame from
|
||||
scratch, then call dupdate().
|
||||
|
||||
/* gray_stop(): Stop the gray engine
|
||||
The gray engine uses the timer id GRAY_TIMER (which is 0) to run and needs 3
|
||||
additional VRAMs (totaling 4), obtained on the heap by default. Timer 0 is
|
||||
chosen for its precision and high priority. If GRAY_TIMER is unavailable or
|
||||
VRAMs cannot be obtained with malloc(), the gray engine will fail to start
|
||||
and this function will return a non-zero error code.
|
||||
|
||||
Safe to call if the engine was not running. The gray engine returns the
|
||||
control of the screen and dupdate() is safe to use again.
|
||||
When functions that use the gray engine call functions that don't and vice-
|
||||
versa, it can be tedious to know exacly when the gray engine should be
|
||||
running. This function provides a stack of gray engine states to solve this
|
||||
problem. When entering a function that uses/doesn't use the gray engine, you
|
||||
can call dgray(DGRAY_PUSH_ON)/dgray(DGRAY_PUSH_OFF) to start/stop the
|
||||
engine; then call dgray(DGRAY_POP) at the end of the function.
|
||||
dgray(DGRAY_POP) will restore the state of the engine as it was before the
|
||||
previous DGRAY_PUSH_*. This allows each function to set its own state
|
||||
without altering the state of their callers.
|
||||
|
||||
This function will leave the screen in whatever state it is, which is most
|
||||
probably one of the gray buffers being displayed. You should dupdate()
|
||||
quickly after this call to avoid visual artifacts. If the next monochrome
|
||||
frame is slow to render, consider rendering it before stopping the gray
|
||||
engine, and calling dupdate() immediately after. */
|
||||
void gray_stop(void);
|
||||
This function returns non-zero if the engine has failed to initialize at
|
||||
startup (because it failed to obtain either GRAY_TIMER or some of its VRAM
|
||||
memory). Because changes to the gray engine only apply after a call to
|
||||
dupdate(), you can check if the engine is successfully initialized with:
|
||||
|
||||
/* gray_delays(): Set the gray engine delays
|

int engine_successfully_initialized = dgray(DGRAY_ON);
|

|
||||
DGRAY_OFF or DGRAY_PUSH_OFF to turn the engine off;
|
||||
DGRAY_POP to restore the state as before the last DGRAY_PUSH_*.
|
||||
|
||||
Returns 0 on success and non-zero if the engine has failed to initialize. */

int dgray(int mode);
|
||||
|

/* dgray_enabled(): Check whether gray mode is enabled
