Added overload for DrawString taking a Point to avoid creating a rect for callers which only use position. This also documents the way DrawString operates when passed a clipping rectangle with a dimension of 0.
As part of this overload removed the logic for 0 width regions from DrawString. This does change the behaviour of the Rectangle version if called with a rect with width 0, all callers using that behaviour have been updated in this commit.
Using Rectangle/Size allowed simplifying the logic for certain calls where they could use DrawText alignment flags, previously this was manually aligning by calculating dimensions and offsetting the position. This also fixes#2169
Also includes a few instances where a temporary buffer was used to set the text to be drawn with unbounded sprintf calls, replaced those with snprintf as is recommended in modern C applications. Moving to C++ strings would be good in a future refactor.
This should gradually replace all the direct rendering of game texts
throughout the code. The interface is made to closly mirror that of the
art fonts as that is what will eventually be used for rendering Unicode
fonts both in the menus and ingame.
fixup! ✨ Generic game text render function
Instead of passing the CEL sprite width when drawing, store the CEL
width at load time in the new `CelSprite` struct.
Implemented for most sprites except towners, missiles, or monsters.
`CelOutputBuffer` now contains an `SDL_Surface` and an `SDL_Rect`.
We now have access to SDL surface manipulation functions.
`gpBuffer` and `gpBufEnd` are completely gone 🧹
This results in some FPS loss (250 -> 195) recovered in a subsequent
commit.
