While I technically finished the 0.2 version of my graphics
engine which has a reasonable speed at low internal resolutions
and with only a couple of sprites, but it still gets bottlenecked
a lot. First I'll throw out the "top-down determination
algorhythm" as it requires constant memory paging (alrought it
made much more sense when the engine was full OO and even slower).
Instead I'll use a overwriting ("bottom-up") method. It still
needs constant updates and I have to remove the per sprite
transparency key and use a per layer key, however it requires
much less paging, and still have the ability of unbound layer
numbers and sprite count with unbound sizes.
I also came up with the idea of reading slices out from the
graphical elements to potentially speed up the process a bit,
especially as the custom bitmaps it uses are 16bit for palette
operations, so per pixel read operations would waste a portion of
memory bus. So should I write a method for the bitmap class which
gets a line from it? (an array slice as it contains the data in a
single 1D array to avoid jagged arrays on a future expansion for
a scaler) And can I write an array slice at a position of an
array? (to reduce writeback calls)
