Jeff Epler 20c9f25a65 rgbmatrix: Eliminate some duplicated height-calculating code
This was hard to write, so let's have it written in 2 places instead
of 4.

Jeff Epler 368977fb90 RGBMatrix: Additional tile tweaks
* Introduce explicit serpentine: bool argument instead of using negative
   numbers (thanks, ghost of @tannewt sitting on one shoulder)
 * Fix several calculations of height

Testing performed (matrixportal):
 * set up a serpentine 64x64 virtual display with 2 64x32 tiles
 * tried all 4 rotations
 * looked at output of REPL

James Bowman dff3423c23 Change from fixed-point integer arguments to floating point in EVE API functions
Changed calls: PointSize(), LineWidth(), VertexTranslateX() and VertexTranslateY()
Units for all the above are now pixels, not fixed-point integers. This matches OpenGL.
Docstrings updated accordingly

Add initial RP2040 support
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.

Jeff Epler f224ed1848 OnDiskBitmap: Correct handling of "0 color palette" images
Microsoft documentation says:

> If biCompression equals BI_RGB and the bitmap uses 8 bpp or less, the bitmap has a color table immediatelly following the BITMAPINFOHEADER structure. The color table consists of an array of RGBQUAD values. The size of the array is given by the biClrUsed member. If biClrUsed is zero, the array contains the maximum number of colors for the given bitdepth; that is, 2^biBitCount colors.

Formerly, we treated 0 colors as "no image palette" during construction,
but then during common_hal_displayio_ondiskbitmap_get_pixel indexed into
the palette anyway.  This could have unpredictable results.  On a pygamer,
it gave an image that was blue and black.  On magtag, it gave a crash.

Jeff Epler 28bd29eb42 displayio: ColorConverter: fix logic errors about transparent pixels
The transparent_color field was never initialized.  I _think_ this means
its value was always set to 0, or the blackest of blacks.  Instead,
initialize it to the sentinel value, newly given the name
NO_TRANSPARENT_COLOR.

This exposed a second problem: The test for whether there was an existing
transparent color was wrong (backwards).  I am guessing that this was not
found due to the first bug; since the converter had a transparent color,
the correct test would have led to always getting the error "Only one
color can be transparent at a time".

Closes #3723

Christian Walther 7ca36d45a4 Fix align32_size().
It not only caused crashes with requests larger than 64K (can happen with RGBMatrix), but also generated a lot longer code than necessary.

Christian Walther a4b84cf0e1 Use movable allocation system for RGBMatrix allocations.
Hybrid allocation is now part of the infrastructure. Moving memory contents would not be necessary because displayio can recreate them, but does not hurt.

Christian Walther ac91220361 Use movable allocation system for Sharp display framebuffer.

Christian Walther c7404a3ff8 Add movable allocation system.
This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap.

By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review.

Add board.DISPLAY to MagTag. Fix luma computation
* Initialize the EPaper display on the MagTag at start.
* Tweak the display send to take a const buffer.
* Correct Luma math
  * Multiply the blue component, not add.
  * Add all of the components together before dividing. This
    reduces the impact of truncated division.
