8e47791e12 Fix BRA imm instruction, add 0xD2 - CMP (zpg) 
I thought 0x80 was a weird NOP imm, but it's BRA.

Implement 0xD2 - CMP (zpg)

Move all 65C02 instruction implementations together

Update disassembler for 0xD2 - CMP (zpg)

2c437b27da record at 50ms simulation per frame 
Change bare "5" to more descriptive "recording_frame_duration_hundredths".

Create APPLE2Einterface events that allow interface to limit main loop speed.

Implement rate limiting on start_record and release limiting on stop_record.

During recording, simulation will not run at clock rate.

dddd18c258 Partially implement animated GIF 
This uses the update rate of OpenGL swapbuffers, but should clock frames by 50ms.

This is 1x sized.  Needs to be 2x sized.

043429311a fix crash if text is dragged from Chrome 
If the drag-and-dropped filename has no leading "/", assume it is
drag-and-dropped text.  This matches the behavior of Chrome on Ubuntu,
for which dragging selected text onto GLFW is passed to the file drop
callback.

If the dragged selected text starts with "/", the drop callback will
still attempt to open it as a filename.
