Bugs to fix:
-  Alignment of ALL .data / .rodata files is required to ensure converted data
   is properly aligned
-  Unpreditcable crap happens when more than 10 keys are pressed simultaneously
-  Ensure heap data is freed when a task-switch results in leaving the app

Things to do before 1.0:
-  bopti:	Test partial transparency
-  demo:	Try 284x124 at (-60, -28) (all disadvantages)
-  project:	Check size of *all* library structures
-  project:	Clean headers that have some internal definitions
-  project:	Get rid of 7705.h (keyboard) and 7305.h (keyboard, gint)
-  time:	Compute CLOCKS_PER_SEC

Things to do later:
-  bopti:	Implement blending modes for monochrome bitmaps
-  clock:	Only measure if requires as option, otherwise trust {FTune}
-  clock:	Handle overclock (relaunch clocks when overclocking)
-  clock:	Split code into several files, change clock_config_t type
-  core:	Change interrupt priority using the gint API
-  core:	Register more interrupts (and understand their parameters)
-  core:	Remove redundant code linked to environment saves
-  core:	Review interrupt system (again) - this one is too slow
-  display:	Try to make this module lighter (lots of code in text section)
-  errno:	Introduce errno and use it more or less everywhere
-  esper:	Cleaner playback, synthesizing
-  events:	Allow customization of keyboard event system (option to return
   |		events with modifiers, etc)
-  events:	Generate keyboard events on-the-fly by reading state arrays,
   |		allowing both a faster interrupt and avoiding supressing other
   |		events inside getkey() and multigetkey()
-  gray:	Same as display, it's quite heavy
-  serial:	Implement a driver
-  stdio:	More serious formatted printing functions and headers
-  string:	Use cmp/str to implement memchr() (assembler examples)
-  string:	Do some tests for memcmp() and memcpy()
-  string:	Lighter functions?
-  usb:		Implement a driver

Things to investigate:
-  Registers that may need to be saved within setjmp()
-  Optimizing core/gint.c leads to raising of an illegal slot exception when
   running the interrupt handler, although it ends on rte; lds.l @r15+, mach,
   which is totally not an illegal slot.

Possibly useful modules:
-  DMAC
-  SCIF, SCIFA
-  TPU
-  USB
-  CMT on SH7305, WDT on SH7705
-  ACD (SH7705 only)
