each "float" in a std140 block would count as 1 component and a "vec4"

limits on uniform buffer loads are surely going to be about the size of

llvmpipe: reduce alignment requirement for 1d resources from 4x4 to 4x1
For rendering to buffers, we cannot have any y alignment.
So make sure that tile clear commands only clear up to the fb width/height,
not more (do this for all resources actually as clearing more seems
pointless for other resources too). For the jit fs function, skip execution
of the lower half of the fragment shader for the 4x4 stamp completely,
for depth/stencil only load/store the values from the first row
(replace other row with undef).
For the blend function, also only load half the values from fs output,
replace the rest with undefs so that everything still operates on the
full 4x4 block to keep code the same between 4x1 and 4x4 (except for
load/store of course which also needs to skip (store) or replace these
values with undefs (load))., at the cost of slightly less optimal code
being produced in some cases.
Also reduce 1d and 1d array alignment too, because they can be handled the
same as buffers so don't need to waste memory.
v2: don't try to run special blend code for 4x1, (very) slightly less
complexity if we just use the same code as for 4x4 which may or may not
make it easier to optimize in the future (as we care a lot more about 4x4
performance than 1d).

multisampled source buffer won't cause a problem for the meta path,
because it uses glReadPixels, which forces a multisample resolve).
It's still safe to assert that the destination image is
single-sampled, because it's not legal to call glCopyTexSubImage() on
multisampled textures.

llvmpipe: reduce alignment requirement for resources from 64x64 to 4x4
The overallocation was very bad especially for things like 1d array
textures which got blown up by a factor of 64. (Even ordinary smallish
2d textures benefit a lot from this, a mipmapped 64x64 rgba8 texture
previously used 7*16kB = 112kB instead of now ~22kB.)
4x4 is chosen because this is the size the jit functions run on, so
making it smaller is going to be a bit more complicated.
It is actually not strictly 4x4 pixel, since we'd want to avoid situations
where different threads are rendering to the same cacheline so we keep
cacheline size alignment in x direction (often 64bytes).
To make this work introduce new task width/height parameters and make
sure clears don't clear the whole tile if it's a partial tile. Likewise,
the rasterizer may produce fragments outside the 4x4 blocks present in a
tile, so don't call the jit function for them.
This does not yet fix rendering to buffers (which cannot have any y
alignment at all), and 1d/1d array textures are still overallocated by a
factor of 4.
v2: replace magic number 4 with LP_RASTER_BLOCK_SIZE, fix size of buffers
allocated (needed in case we render to them).

In traditional multisampled framebuffer rendering, color samples must be
explicitly resolved via BlitFramebuffer before doing the scaled blitting
of the framebuffer. So, scaled blitting of a multisample framebuffer

This patch implements the functionality of doing multisampled scaled
resolve using just one BlitFramebuffer call. Important changes involved
in this patch are listed below:
- Use float registers to scale and offset texture coordinates.
- Change offset computation to consider float coordinates.
- Round the scaled coordinates down to nearest integer.
- Modify src texture coordinates clipping to account for scaling..
- Linear filter is not yet implemented in blorp. So, don't use
