5bb6245b1f softgpu: Fix leaked range flag on cull. 
Fixes some backgrounds in Final Fantasy 4, probably others.

0b73c1ce83 softgpu: Correct guardband cull behavior. 
Culling is based on whether clipping happens, not whether clamping
happens.  This is important for issues like #12348.

2f63f9999d GPU: Normalize 0 to 1 always in software lighting. 
See #14167.  This seems to be consistent.

c5e0b799d9 Remove category from _assert_msg_ functions. We don't filter these by category anyway. 
Fixes the inconsistency where we _assert_ didn't take a category but
_assert_msg_ did.

c7f6724f7e Detect sprite drawing (1:1 texture mapping), run a simpler function without the triangle state tracking. 
This will allow further simplification and specialization.

3c5455f85b SoftGPU: Calculate texcoords in transform. 
No need to do it in rasterization, and should be faster to do it on the
verts, anyway.  This fixes the software issue of #11595, presumably
because of the w handling.

11a8857a7e SoftGPU: Correct clipping for flat shading. 
It needs to use the provoking color, regardless of culling or clipping.

Fixes Blade Dancer lighting (see #4140.)

797327eecd GPU: Handle bad fog params as large signed vals. 
From tests, it seems they're just treated as valid exponents.

Using 65535 since that's the range of depth, can't think of a game using a
larger value for a fog parameter, probably never even this large.

cd6b1f73c1 SoftGPU: Drop verts only when depth not clamped. 
Depth clamping bypasses the 4096x4096 box check.

77f0499f7f GPU: Rename clipping flag to depth clamp. 
It seems to just to depth clamp.  When depth clamp happens, it affects
clipping a little, but only for vertices that needed clamping.

8187927b9d SoftGPU: Use vertexjit for submitted primitives. 
This uses the standard cache other rendering uses.

In Legend of Heroes 3, for example, this provides a 10% speed improvement.

01076dd959 SoftGPU: Don't wrap negative positions. 
Haven't fully verified this, but without this, Gods Eater Burst's bloom
doesn't work, since -1,-1 maps to 1023,1023 so everything is clipped.
