Fixes #5779 with new PSPScreenShotDiag class
Only set depth update flag when depth write is enabled
Switch to a slider for alternative speed, and make its range 5-600%.
Allow the speed to go as low as 0% (at which point it becomes unlimited, since zero FPS limit in the code means unthrottle).
Oops, the vertexdecoder should read vertex alpha.

Copy/paste mistake... ugh.
Don't forget tex alpha if only a mip has none.

Mip levels should only move toward unknown.
Avoid the GE debugger affecting vertexFullAlpha.
Use an unsigned compare for x86 vertexalpha check.

Fix a bunch of texture/vertex alpha issues
Alt speed slider: Remove the rounding, since native does it automatically. Don't use an integer divide.

Alternate Speed slider: don't round and don't use an integer divide.

Fixes #5779 with new PSPScreenShotDialog class
Make sure to gen the frag shader matching the id.

Otherwise, the frag shader might be generated accounting for different
vertexFullAlpha values, or otherwise won't match up with the id, since we
change flags between the two Apply calls.
Fix a couple ARM VFPU flags.
Unknown's explanation:
LO means Lower (unsigned), but for floats, it means "Less than".
LT means Lower (signed), but for floats it means "Less than OR unordered".
ARM docs at http://infocenter.arm.com/help/topic/com.arm.doc.dui0068b/Chdhcfbc.html explain the following:
LE means Signed less than or equal, and for floats it means "Less than or equal, or unordered".
LS means Unsigned lower or same, but for floats, it means "Less than or equal"
Improve reset (and delay) and boot of another game.
