Speed up raw drawing by calling EventAvail and SystemTask less often.
...
They are now called only every 16 lines, instead of every line. This is enough to maintain reasonable responsiveness, while providing a measurable speedup.

Use faster assembly routine for 320-mode raw pixel decoding too.
...
The assembly code for the 640-mode and 320-mode routines is moved to a macro so it can be shared between them.

Switch to using faster assembly routine (instead of C) for 640-mode pixel decoding loop.

Use a static (instead of dynamically allocated) buffer for SHR pixels generated from raw decoding.
...
The program code is moved to a separate segment to make room for the buffer.

Clean up headers and make things static where appropriate.
...
Also include a few missing prototypes, which could possibly fix bugs.

Statically allocate space for color tables in an assembly file.
...
This is a prelude to rewriting the raw decoding logic in more efficient assembly code.

Fix a memory leak in ReadFixup.
...
The buffer from the last read is still left around until the next one, but this should usually be fairly small, and it's the same behavior as the main DoReadTCP routine.

Optimize 640 mode raw decoding for case where consecutive blocks of 4 pixels are the same.
...
This is also a win provided it can use the optimized case over ~40% of the time.

Optimize 320-mode raw pixel decoding for the case where two consecutive pairs of pixels are the same.
...
This is only a win if we can use the optimized case a reasonable proportion of the time (~40% or more), but that should be the case for most real screen images.
The equality comparisons are written with XORs because that produces better assembly code.

Raw decoding optimization: Do operations using 16 bits where possible.
...
This saves a few instructions that were being used to switch to 8-bit mode or mask values down to 8 bits.

Optimize the core loops for decoding raw pixels a little, in particular deferring increments to the end.

Use 16-bit computations for shifts, where possible.
...
This causes ORCA/C to generate better code, using shift instructions rather than function calls.

Replace a few mod-by-power-of-2 operations with bit masking, since ORCA/C wasn't optimizing them

Terminate blocking reads on TCP errors, instead of waiting for timer to expire.
...
This should avoid most cases where the program seems to hang for 15 seconds.

Flip the mapping of OA (Command) and Option keys.
...
This matches the de facto standard of Mac VNC implementations, although it's inconsistent with the labeling of Option as "Alt."
