* 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 change adds a new HWCALC model, HWCALC_FXCG_MANAGER, which
identifies Casio's official fx-CG Manager software. Both the Prizm and,
to my surprise, the fx-CG Manager use the old RAM address of 88000000
(P1) and a8000000 (P2) instead of the new fx-CG 50 address of 8c000000
(P1) and ac000000 (P2).
The VRAM is hence adjusted at startup to move hardcoded pointers into
the proper space. Added to the kernel moving the VBR space dynamically
on the Prizm, this allows gint to be fully compatible with these
platforms.
The fx-CG Manager is detected by its product ID made of 0xff.
Also adds a proper interface to the R61524 driver, even though it's not
any more complete than previously, and fixes an oversight where the
HWURAM entry of the kernel data array was no longer computed since the
TLB management change.
As of now, the fx-CG Manager still has a bug regarding return-to-menu
since returning from the main menu doesn't work very well and often
loops. This has been seen occasionally on some Graph 90+E so it's
unlikely to be a platform-specific problem.
t6k11: use the gint array for variant detection
r61524: use true triple buffering by default
display: define DWIDTH and DHEIGHT
display: add C_RGB(r,g,b) (0 ≤ r,g,b ≤ 31) [fxcg50]
This macro used to protect the declaration of the [vram] variable of
gint. This variable was short to keep drawing functions short but could
clutter the namespace.
That being said, it's even better to just [#define vram gint_vram] if
you need. This change renames the variable to [gint_vram], exposes it
whenever <gint/display.h> is included, and removes the GINT_NEED_VRAM
macro altogether.
